Test software

SAT (semi-automatic test) module is a PC with installed frame grabber card and specialized software optimized for testing surveillance imaging systems or modules of such systems. Generally SAT module enables capture and analysis of images generated by tested electro-optical imaging systems like thermal imagers, TV cameras or video cameras used in the test system.. The PC is the heart of the SAT module and is connected both to the test system and to the tested imager.

Standard PCs (desktop PC or laptop) are used as part of SAT module. Standard frame grabber card enables acquisition of electronic image in the following formats: analog video (PAL, NTSC) or digital (Fire Wire, USB 2.0). Optional frame grabber can capture electronic images in the following digital formats: LVDS, CameraLink or GigE.

Specialized software is offered in different versions depending on type of test system. Typically the software package is built from TAS series program for image analysis and some additional programs for control of blackbody/light source. TAS is an advanced computer program optimized for analysis of images generated by surveillance imaging systems and calculation of parameters of these systems.
