Introduction Computer System Requirements • Intel Pentium Dual Core or AMD equivalent • Operating Systems: Windows 7 / 8.1 / 10 (64 or 32-bit) or • RAM min. 4 GB, depending on the size of acquired Linux kernel 3.13 or higher images •...
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 collar • If the camera and the optics are ordered as a kit, for the mounting bracket SK5105 (available as an the components are pre-assembled and shipped accessory).
Installation and Setup Electrical Installation: Connections and I/O Signals • The USB 3.0 interface provides data transfer, camera control and power supply capabilities to the SK2048U3HA 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 USB3 Connections and SkLineScan Software Installation This section is a quick reference for installing the SkLineScan adjustment and configuration software and to set up the USB3 camera driver. SkLineScan and the SkLineScan manual is provided for download on the Schäfter + Kirchhoff website under http://www.sukhamburg.com/support.html.
Camera Control and Performing a Scan Camera Control and Performing a Scan Software: SkLineScan This section is a brief introduction to the SkLineScan adjustment and configuration software. A more detailed description is provided in the separate SkLineScan manual. The pdf is included in the SkLineScan installation package or is available for download from the Schäfter + Kirchhoff website under http://www.sukhamburg.com/ supporte.html.
Camera Control and Performing a Scan 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 •...
Camera Control and Performing a Scan Sensor Alignment If you are using a linear light source, check the alignment of the light source and sensor before shading correction, as rotating the line sensor will result in asymmetric vignetting. Sensor and line lighting slightly twisted in Sensor and line lighting aligned in parallel, relation to each other, asymmetric vignetting symmetric vignetting...
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 of a white homogeneous background is used as a reference. For correction, each pixel of the sensor is scaled to the intensity maximum with an individual factor (255 at 8 bit resolution and 4095 at 12 bit).
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 generated using API (Application Programming Interface) functions. The relationship between the memory locations and the related API functions are shown in the following figure.
Camera Control and Performing a Scan Synchronization of the Image Acquisition with the Feed Rate of the Object A line scan camera produces a two-dimensional image by moving either the object or the camera. The direction of the translation movement must be orthogonal to the sensor axis of the line scan camera. In order to obtain an image with the correct aspect ratio, a line synchronous feed is required.
Camera Control and Performing a Scan Synchronization Modes The synchronization mode determines the exact timing of the exposure. Synchronization can either be performed internally or triggered by an external source, e.g. an encoder signal. There are two different synchronization functions that can be applied together or individually: 1.

Camera Control and Performing a Scan • To configure synchronization, open the Camera Control dialog. [F4] • Within the Synchronization frame, select one of the numbered line synchronization modes. • Within the camera, the trigger control stage is followed by a divider stage with which the trigger frequency can be divided by integer dividers.
Advanced Camera Control Functions Advanced Camera Control Functions Camera Control by Commands In addition to user dialog inputs, the SkLineScan software also provides the option to adjust 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 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 Blooming The optical resolution of the line sensor is primarily determined by the number of pixels and secondarily by If by overexposure too many charge carriers are produced their size and spacing, the inter-pixel distance. Currently in one or several photosensitive elements (pixels) of the available line scan cameras have up to 12 000 pixels, line sensor, the transport register is „flooded“...

SkLineScan is the software application from Schäfter + Kirchhoff for controlling and adjusting the line scan cameras, Software: SkLineScan, section 3.1 Synchronization To obtain a proportional image with the correct aspect ratio, a line synchronous transport with the laterally correct pixel assignment is required.
