Schäfter+Kirchhoff mainly provide digital line scan cameras, although
legacy analog line scan cameras can be supplied for backward
compatibility. The line scan signal is digitized with 8 or 12-bit
resolution directly in the digital line scan camera, which can be
supplied with either GigE Vision™, LVDS, CameraLink® or USB 2.0
interfaces for data output.
Schäfter+Kirchhoff now also provides the latest industrial standard interface, GigE Vision™,
for monochrome and color line scan cameras, for TDI and the other
special-purpose line scan cameras with integrated bright-field
illumination. Signal preprocessing, such as thresholding and shading
correction, is performed within the camera and does not impinge on CPU
use. These cameras work with standard network components, a grabber
board is unnecessary and data cables of up to 100 meters long are
Cameras with the LVDS interface are operated by the
Schäfter+Kirchhoff SK9192D line scan PCI grabber board, especially
developed for line scan cameras. Signal preprocessing, including
thresholding, windowing and shading correction are all performed
on-board. A Schäfter+Kirchhoff merger box enables the line-synchronous
operation of multiple line scan cameras using one grabber board.
Cameras with the CameraLink® interface fit seamlessly into systems where a CameraLink® grabber board is already used.
Cameras with the USB 2.0 interface are the primary choice for
mobile applications or those involving multiple PCs, such as
transportable measurement systems or educational and scientific
experiments operated from a laptop.
