11.8 Test Images
Figure 11.14: LFSR (linear feedback shift register) test image
In the LFSR (linear feedback shift register) mode the camera generates a constant
pseudo-random test pattern containing all grey levels. If the data transmission is correctly
received, the histogram of the image will be flat (Fig. 11.15). On the other hand, a non-flat
histogram (Fig. 11.16) indicates problems, that may be caused either by a defective camera, by
problems in the acquisition software or in the transmission path.

In robots applications, the stress that is applied to the camera cable is especially high due to
the fast movement of the robot arm. For such applications, special drag chain capable cables
are available. Please contact the Photonfocus Support for consulting expertise.
