1.2  System Setup at a Glance

The SK line scan camera series is designed for a wide 
range of vision and inspection applications in industrial 
and scientific environments. The SK8100U3JRC is highly 
portable and the robustly attached dedicated connections 
enable external synchronization of the camera and the 
output of data to the USB 3.0 port of the computer.
The USB 3.0 connection supplies power to the camera 
and the camera is hot-pluggable, providing the greatest 
degree of flexibility and mobility. The computer does not 
require a grabber board, allowing a laptop to be used 
when space or weight restrictions are also at a premium.

Once the camera driver and the SkLineScan

®

 program 

have been loaded from the SK91USB3-WIN CD then the 
camera can be parameterized. The parameters, such as 
integration time, synchronization mode or shading 
correction, are permanently stored in the camera even 
after a power-down or disconnection from the PC. 
The oscilloscope display in the SkLineScan

®

 program 

can be used to adjust the focus and aperture settings, for 
evaluating field-flattening of the lens and for orientation 
of the illumination and the sensor, see
