    How to get started (CameraLink) Install a suitable frame grabber in your PC. To find a compliant frame grabber, please see the frame grabber compatibility list at www.photonfocus.com. Install the frame grabber software. Without installed frame grabber software the camera configuration tool PFRe- mote will not be able to communicate with the camera.
  • Page 12 2 How to get started (CameraLink) The sensor has no cover glass, therefore dust on the sensor surface may resemble to clusters or extended regions of dead pixel. To choose a lens, see the Lens Finder in the ’Support’ area at www.photonfocus.com.
  • Page 13 Download the camera software PFRemote to your computer. You can find the latest version of PFRemote on the support page at www.photonfocus.com. Install the camera software PFRemote.

    4 Functionality 4.2 Image Information There are camera properties available that give information about the acquired images, such as an image counter, average image value and the number of missed trigger signals. These properties can be queried by software. Alternatively, a status line within the image data can be switched on that contains all the available image information.

  • Page 25: Pixel Response

    4.3 Pixel Response 4.3.1 Linear Response The camera offers a linear response between input light signal and output gray level. This can be modified by the use of LinLog or Skimming as described in the following sections. In addition, a linear digital gain may be applied, as follows. Please see Table 3.2 for more model-dependent information.
  • Page 26 4 Functionality LinLog is controlled by up to 4 parameters (Time1, Time2, Value1 and Value2). Value1 and Value2 correspond to the LinLog voltage that is applied to the sensor. The higher the parameters Value1 and Value2 respectively, the stronger the compression for the high light intensities. Time1 and Time2 are normalised to the exposure time.
  • Page 27 LinLog2 To get more gray resolution in the LinLog mode, the LinLog2 procedure was developed. In LinLog2 mode a switching between two different logarithmic compressions occurs during the exposure time (see Fig. 4.11). The exposure starts with strong compression with a high LinLog voltage (Value1).

The input voltage to the TRIGGER pin must not exceed +15V DC, to avoid damage to the internal optocoupler! In order to use the strobe output, the internal optocoupler must be powered with 5 .. 15 V DC. The STROBE signal is an open-collector output, therefore, the user must connect a pull-up resistor (see Table 5.1) to STROBE_VDD (5 ..

    5.3 Read-out Timing 5.3.1 Free running Mode Sequential readout timing By default, the camera is in free running mode and delivers images without any external control signals. The sensor is operated in sequential readout mode, which means that the sensor is read out after the exposure time. Then the sensor is reset, a new exposure starts and the readout of the image information begins again.

    5.4 Trigger 5.4.1 Trigger Modes The following sections show the timing diagram for the trigger modes. The signal ExSync denotes the trigger signal that is provided either by the interface trigger or the I/O trigger (see Section 4.6). The other signals are explained in Table 5.4. Camera-controlled Exposure In the camera-controlled trigger mode, the exposure is defined by the camera and is configurable by software.
  • Page 56 5 Hardware Interface Level-controlled Exposure In the level-controlled trigger mode, the exposure time is defined by the pulse width of the external trigger signal. For an active high trigger signal, the image acquisition begins with the rising edge and stops with the falling edge of the external trigger signal. Then the image is read out.

  • Page 57: Trigger Delay

    5.4.2 Trigger Delay The total delay between the trigger edge and the camera exposure consists of the delay in the frame grabber and the camera (Fig. 5.12). Usually, the delay in the frame grabber is relatively large to avoid accidental triggers caused by voltage spikes (see Fig. 5.13). The trigger can also be delayed by the property Trigger.Delay.
  • Page 58 5 Hardware Interface For the delay in the frame grabber, please ask your frame grabber manufacturer. The camera delay consists of a constant trigger delay and a variable delay (jitter).
