Installation and Setup Installation and Setup Mechanical Installation: Mounting Options and Dimensions Mounting Options Optics Handling • The best fixing point of the camera is the seat for • If the camera and the optics are ordered as a kit, the mounting bracket SK5105, which is available as the components are pre-assembled and shipped as an accessory.
Electrical Installation: Connections and I/O Signals • The USB 3.0 interface provides data transfer, camera control and power supply capabilities to the SK1024U3PD line scan camera. If you want to operate the camera in Free Run (SK Mode 0) trigger mode the USB 3.0 cable is the only connection you have to make.
Installation and Setup Software Installation • The PC hardware requirements are listed in section 1.3 Computer System Requirements, p. 4 • See section 2.2 Electrical Installation: Connections and I/O Signals, p. 6. prior to software installation. • This section focusses on driver installation and initial operation of the camera. For a comprehensive description of the software package, see the separate SK91USB3-WIN software manual.
Camera Control and Performing a Scan Software: SkLineScan Start the SkLineScan program. • If the SK1024U3PD camera is identified correctly confirm with "OK". The "Signal window" graphicaly showing the intensity signals of the sensor pixels • The most common functions of the line scan camera (oscilloscope display) will open.
Camera Control and Performing a Scan Basic Visualization of the Sensor Output Signal Window / Oscilloscope Display The signal window plots the digitalized brightness profile as signal intensity (y-axis) versus the sensor length (x-axis) at a high refresh rate. The scaling of the y-axis depends on the resolution of the A/D converter: The scale range is from 0 to 255 for 8-bits and from 0 to 4095 for 12-bits.
Camera Control and Performing a Scan Adjustments for Optimum Scan Results Prior to a scan, the following adjustments and parameter settings should be considered for optimum scan signals: • Lens focussing • Integration time • Sensor alignment • Synchronization of the sensor exposure and the object surface velocity, trigger mode •...
Camera Control and Performing a Scan Sensor Alignment If you are operating with a linear illumination source, check the alignment of the illumination source and the sensor prior to a shading correction, as rotating the line sensor results in asymmetric vignetting. Sensor and optics rotated in apposition Sensor and optics aligned Gain/Offset Control Dialog...
Camera Control and Performing a Scan Shading Correction Shading Correction compensates for non-uniform illumination, lens vignetting as well as any differences in pixel sensitivity. The signal from a white homogeneous background is obtained and used as a reference to correct each pixel of the sensor with an individual factor, scaled up to the intensity maximum (255 at 8-bit resolution and 4095 at 12-bit) to provide a flat signal.
Camera Control and Performing a Scan Shading Correction Memories and API Functions As an alternative to the user dialog, a new shading correction reference signal can also be created by using appli- cation programming interface (API) functions. The relationshhip between the storage locations and the related API functions are shown in the diagram below.
Camera Control and Performing a Scan Synchronization of the Imaging Procedure and the Object Scan Velocity • A two-dimensional image is generated by moving either the object or the camera. The direction of the translation movement must be orthogonal to the sensor axis of the CCD line scan camera. To obtain a proportional image with the correct aspect ratio, a line synchronous transport with the laterally •...

Each single line scan is triggered by the falling edge of a TTL signal supplied to LINE SYNC A input. The SK1024U3PD line scan camera facilitates advanced synchronization control by a second trigger input LINE SYNC B. For a detailed description see Advanced Synchronization Control, p.
Advanced SkLineScan Software Functions Advanced SkLineScan Software Functions Camera Control by Commands In addition to user dialog inputs, the SkLineScan software also provides the option to adjust any camera settings, such as gain, offset, trigger modes, by sending control commands directly. Similarly, current parameters, as well as specific product information, can be read from the camera using the request commands.

Advanced SkLineScan Software Functions Advanced Synchronization Control The basic synchronization function makes use of the trigger input LINE SYNC A. The trigger mode is determined by the settings in the "Camera Control" dialog, e.g. LineStart (1) or ExposureStart (4). Advanced trigger functions are provided by combining LINE SYNC A with a second trigger input LINE SYNC B. The operation mode is controlled by the entries in the Sync Control Register (SCR).
Advanced SkLineScan Software Functions Example Timing Diagrams of Advanced Synchronization Control Annotations: SyncA = LINE SYNC A (external line synchronization input, I/O connector) SyncB = LINE SYNC B (external line synchronization input, I/O connector) Count = internal counter Trigger = Generated trigger pulses from the Trigger Control stage. The signal goes to the Trigger Divider stage inside the camera.
Glossary Shading correction Exposure period is the illumination cycle of a line scan sensor. It is the Shading Correction, p. 17 integration time plus the additional time to complete the read-out of the accumulated charges and the output procedure. While the charges from a finished line scan are being read out, the next line scan is being exposed.
