    Introduction to Microbolometers A microbolometer is an uncooled thermal sensor used as a detector in an infrared camera. FLIR A68/A38 series cameras are sensitive to thermal energy at long wave infrared (LWIR) wavelengths ranging from 8 μm to 14 μm (infrared wavelengths span from 710 nm –...

  • Page 24: Emissivity

    The IR absorbing material is thermally isolated by suspending it within a vacuum, however it is still sensitive to changes in the camera body temperature. When the camera operating temperature changes, the FLIR A68/A38 series shutterless operation automatically compensates for the corresponding responsivity changes in the microbolometer pixel array (non-uniformity correction (NUC)).

  • Page 30: Displaying Images

    Displaying Images The FLIR A68/A38 series sensor outputs 16-bit images, but these images cannot be displayed directly; for display they must be converted to 8-bit images. This can be done by the camera (see the Contrast Enhancement section) or by the host application. Displaying 16-bit Images In CamExpert, under the Image Format Controls Category, select Pixel Format = Monochrome 16-Bit.

  • Page 36: Heat Sinks

    Basic heat management is achieved by mounting the camera onto a metal structure via its mounting screw holes. Teledyne FLIR recommends that the FLIR A68/A38 series camera be mounted using heat sinks to optimize shutterless operation. Refer to the Mechanical Specifications section for information on the exact size and position of the camera mounting holes.

  • Page 37: Led Indicators

    LED Indicators The FLIR A68/A38 series has one multicolor LED to provide a simple visible indication of camera state conditions. FLIR A68/A38 Series LED States After the A68/A38 connects to a network and an IP address is assigned, the Status LED will turn to steady blue.

  • Page 38: Fixed Pattern Noise Correction

    Fixed Pattern Noise Correction FLIR A68/A38 series cameras are factory calibrated to correct for fixed pattern noise. The camera dynamically corrects the sensor response across the entire range of the camera’s ambient operating temperature using the factory calibration. If the thermomechanical conditions of the camera differ significantly from the factory calibration conditions, non-uniformities or unwanted artifacts may be seen in the sensor response (for example, a halo or vignetting effect).

  • Page 39: Saving Fixed Pattern Noise Calibration

    Saving Fixed Pattern Noise Calibration After calibration, the FPN calibration coefficients can be saved to non-volatile camera memory. When enabled, the FPN correction is applied in addition to the default factory calibrated non-uniformity correction. FPN Compensation Mode = Active FPN Compensation Mode = Off Figure 5: FPN Compensation Mode Note: FPN correction is only valid at the operating temperature at which it was calculated;...

    For information on troubleshooting the internal mechanical shutter, refer to the Internal Shutter Problems section. Performing Manual FPN Correction with External Shutter 4. With the camera at nominal operating temperature, expose the camera (with the lens) to a scene of uniform temperature. For example, this can be done using an object with a flat surface, ideally matte black and non-reflective, such as a metal plate.

  • Page 42: Fpn Correction Using Triggered Acquisition

    FPN Correction Using Triggered Acquisition FPN correction provides the best image quality if FPN calibration is performed under normal operating conditions. This depends on how the sensor is triggered: TriggerMode is set to Off or the Exposure Alignment Mode (readoutAlignment) is set to FreeRunning, then the camera is constantly acquiring images from the sensor.

  • Page 43: Performing Calibration Of The Supplemental Fpn Correction Table

    Performing Calibration of the Supplemental FPN Correction Table When performing an FPN calibration with the internal shutter, some non-uniformities can remain in the image. These are due to the distribution of heat in camera components, such as the camera casing and lens, that are ‘hidden’ by the internal shutter when it is closed.

  • Page 44: Radiometry

    Radiometry The A68/A38 series cameras support radiometric temperature measurements as a stand-alone GigE camera or as an integrated OEM part of another system. In both cases, certain integration considerations are essential to obtain the highest camera accuracy and performance. This section highlights the most important aspects of such an integration.
  • Page 45 Conversion From an 8-Bit Image Conversion from a monochrome 8-bit image to a temperature is more indirect. Since the camera maps the sensor’s 16-bit output to an 8-bit image for display, the relationship between pixel value and temperature depends upon the contrast mode (see feature contrastMode): For Static (fixed range in DN value) and StaticTemperature (fixed temperature range) modes, the camera maps the sensor’s pixel value...

  • Page 46: Mounting And Thermal Considerations

    The FPGA inside the camera must always be maintained at a temperature at or below 85°C. Teledyne DALSA recommends connecting the camera to the system by the bottom mounting holes of the camera, preferably having some metallic part connected thermally to the chassis of the system fully pressed against the whole surface of the camera bottom.

  • Page 47: Figure 10: Camera Mounted On Tripod

    To the extent possible, the camera, while thermally connected to the system/environment, should be insulated from rapid temperature swings and changes in airflow. Extreme thermal shock reduces the effectiveness of calibration and degrades the quality of the image and the accuracy of the reading. For example, if the camera is only mounted on a tripod the ambient temperature change will influence the complete camera thermal behavior leading to a less accurate temperature reading.

  • Page 48: Figure 12: Influence Of Airflow On Temperature Accuracy

    However, NUC correction considers the deltas between the camera’s different component’s temperatures (lens/shutter/mechanics/sensor). Significant changes to the thermal connection of the camera to the environment or in airflow around the camera will affect the signal coming from these parts and can require an adjustment of the reference level of measurements.

  • Page 49: Using Enclosures

    thermal cameras are generally mounted inside a box (enclosure) with an IR transparent window. Using Enclosures Avoid mounting conditions and enclosures which expose the camera to asymmetric heating from systems and other heat sources. If air cooling is present in the system, airflow should be directed away from the camera/lens/window and as much as possible be constant and symmetric around the optical line of sight.

  • Page 50: Radiometric Calibration

    If a window is added in front of the lens as part of the design (window enclosure for example), both slope/gain and offset need to be readjusted to compensate for transmission loss. If the window material does not have sufficiently high transmission, window temperature and transmittance need to be considered in the correction values applied.
  • Page 51 Initial Feature Settings For radiometric calibration, set the following feature values: In the Image Format Controls category, set the “Pixel Format” (PixelFormat) to “Monochrome 16-Bit”. In the Image Processing category: • Set “Noise Filter Mode” (noiseFilterMode) to “Medium” • Set “Median Filter Mode” (medianFilterMode) to “Selective” •...
  • Page 52 Calculating the Gain Acquire a first image and measure the mean output of the ROIs corresponding to the active area of the blackbodies. The goal is to have multiple data points to establish the relationship between pixel values (in DN) and the related scene temperature (in °C) If you are using at least two blackbody radiators, the image displayed in CamExpert contains all the data required for gain calibration.

  • Page 53: Figure 15: Gain Feature For External Optic Adjustment

    Data Analysis: Gain Correction Perform a linear regression on these mean DN values to find the slope [DN/°C]. The line of best fit is described by the equation Y (DN) = bX (Temperature) + a, where b is the slope of the line and a is the intercept (that is, the value of Y when X = 0). The gain to apply is simply 100 over the computed slope (100/b).
  • Page 54 Calculating the Offset After the gain correction has been entered into the camera, the offset correction can be calibrated. There are two methods to perform this: • Manual correction: when the “Radiometry Offset Correction Mode” (radiometryOffsetCorrectionMode, found under CamExpert’s Contrast / Brightness / Radiometry category) is set to “Manual”, the offset correction is static.

  • Page 55: Figure 16: Radiometric Offset Correction Feature

    This value can then be applied to the camera; set the Radiometry Offset Correction Mode to Manual, then set the value of “Radiometry Offset Correction” (radiometryOffsetCorrection) to the computed offset value (typically a negative value). Figure 16: Radiometric Offset Correction Feature Offset Correction: Automatic Mode Since most error sources manifest as a global temperature offset, having a known temperature source from a blackbody radiator as part of the scene provides a...

    To use an external blackbody reference: 1. In CamExpert, enable the overlay control using the features available in the Overlay Control category: • Overlay Global Mode: Active • Overlay Selector: Zone 1 • Overlay Mode: Active Figure 18: Overlay feature setup for external reference 2.

  • Page 57: Overlays

    Overlays The FLIR A68/A38 series camera can enable graphic overlays in the output image. Available overlays include: a reticle, colormap legend, frame counter, metadata, zone corners and alarm status. Each overlay can be individually enabled/disabled. Their positions are configurable. A global overlay mode parameter allows turning on or off all enabled overlays.

  • Page 58: Related Gige Vision Features

    • The status of the Alarms can be reported as pixel values in the image. The location of the overlay can be specified and consists of a consecutive segment of 3 pixels, each representing an alarm, with the pixel value 0 indicating Off and the highest pixel value for the image format indicating On (255 or 65545 for 8 and 16-bit;...

  • Page 59: False Color Mapping

    False Color Mapping The camera supports the use of false color to enhance contrast or reduce eye fatigue. To use a false color mapping the pixel format must be set to YUYV. The following color maps are available: • Greyscale: 8-bit monochrome •...

  • Page 60: Metadata

    Metadata Along with each image, the A68/A38 camera can optionally output metadata associated to that image. Metadata is appended to the image data: To accommodate the metadata information the image buffer height (allocated by the host application) must be increased by 2 lines (buffer height = image height +2). For example, if the image size is 640 x 480, the allocated buffer height is 482.
  • Page 61 The metadata contains the following values, in this order: Type Value Description unsigned short revision; Version of the metadata structure. unsigned short size; Total size of the metadata (including a number bytes reserved for future use). unsigned char [16] serialNumber; String representing the serial number of the camera that generated the image.

  • Page 64: Defective Pixel Correction

    Defective Pixel Correction The FLIR A68/A38 series camera uses a defective pixel map to identify bad pixels in the sensor. These bad pixels are replaced by the average value of neighboring valid pixels. The defective pixel map is an 8-bit bitmap file (.bmp) that uses two pixel values;...

  • Page 65: Related Gige Vision Features

    Use the Detect Defective Pixels feature (defectivePixelDetectionTrigger) to perform defective pixel detection. Note: Automatic defective pixel detection only adds pixels to the list of defective pixels, therefore it can be run at different ambient operating temperatures to identify pixels that do not respond well at certain temperatures only.

  • Page 66: Median Filter

    Median Filter The FLIR A68/A38 series camera can apply a median 3x3 filter to perform image smoothing. This filter is applied to the entire image and can be used to reduce image noise and other artifacts. The following examples use a zoomed image to show the effects of the median filter at pixel level.

  • Page 67: Contrast Enhancement

    Contrast Enhancement The native output of the FLIR A68/A38 series sensor is 16-bits. The contrast enhancement mechanism is implemented when the pixel output is 8-bits. Contrast enhancement maps the 16-bit image to 8-bits to output high quality, well-contrasted images, regardless of the temperature differences found in the scene. Note: For GigE Vision digital output, the camera output pixel format can be set to either 16 or 8-bits (monochrome or YUYV).

  • Page 68: Figure 28: Dynamic Adaptive Image Enhancement

    When using adaptive modes, the image region used to calculate the contrast/brightness adjustments can be limited to a specific contrast zone (using the features available in the Contrast / Brightness category). This can be useful if the image scene contains distinct regions (for example, a horizon with sky and landscape) and the area of interest resides in one region;...

  • Page 70: Figure 29: Contrast Enhancement Maximum Gain

    Maximum Gain The maximum gain feature is used when the Contrast Mode (contrastMode) feature is set to Dynamic Adaptive (AdaptiveDynamic). This feature only applies when the 16-bit image has low contrast (image range is less than 255 DN). The maximum gain setting determines the smallest range of 16-bit values (around the average value) that can be stretched to fit 8-bits (0-255).

  • Page 71: Table 10: Maximum Gain Off Example

    For example, using the following sample image, the dynamic adaptive contrast mode stretches the image automatically (max gain feature = off) such that the resulting 8-bit image uses most of the dynamic range available (~215 DN) without saturating. This results from the fact that the dynamic adaptive contrast has calculated a gain of ~1.5 to apply to the image.

  • Page 72: Figure 30: Fixed Adaptive Image Enhancement

    Table 12: Maximum Gain Setting 0.5 Example Image 8-Bit Image Histogram Max Gain = 0.5 Fixed Adaptive Mode The fixed adaptive mode uses a fixed range based on the contrast setting to map pixels from 16-bit to 8-bit. The size of this range does not change, regardless of the scene content, ensuring a constant contrast.

  • Page 73: Figure 31: Fixed Adaptive Brightness Setting

    The fixed adaptive mode also provides a Brightness (brightness) feature that shifts all pixel values higher (brightness > 128) or lower (brightness < 128). Fixed Adaptive Brightness Setting Average Pixel Value Lower Brightness Higher Brightness 8-bit Histogram Figure 31: Fixed Adaptive Brightness Setting This provides a mechanism to darken or brighten the image to reveal details from over-saturated or dark regions, while maintaining the contrast.

  • Page 74: Table 13: Sample 16-Bit Image

    Static Contrast Mode (Fixed Range of DN Values) This is the camera operation used when the feature contrastMode is set to Static. This static contrast mode maps a fixed range in the 16-bit image to 8-bit values. The minimum and maximum input values (contrastMinValue and contrastMaxValue features) specify the range of values in the 16-bit image.

  • Page 75: Table 14: Static Contrast Mode Example

    Given the minimum and maximum values are 30021 and 33023, respectively, the static minimum and maximum gain values can be set accordingly, slightly outside this range so that the resulting image utilizes as wide a dynamic range as possible, without saturating at higher values or clipping at lower values..
