The TVT test station  is a variable intensity image projector that projects images of some standard targets to the tested TV camera (CCD/CMOS/ICCD/EBAPS cameras) The tested TV camera generates distorted copies of the projected images. Quality of the images generated by the camera is evaluated and its important characteristics are measured.  The TVT test systems are built from the following blocks:  DAL series calibrated light source, set of targets, rotary wheel, set of exchangeable refractive/reflective collimators, PC, frame grabber, TAS-TV software, OS stage. 

The TVT test systems are recommended for testing  TV cameras used for medium/long distance surveillance. The TVT test systems can be delivered in several versions optimised to applications of tested TV cameras (day, night, day/night).
