Unified photodetector (FPU) FPU-1024M is based on CCDs resistant to space environment ionization radiation with 1024×1024 pixels to provide output signal reading out.
FPU consists of CCD unit, CCD signal control and process unit, CCD units power supply, and package with electrical sockets to connect primary power sources and to transfer control signals from board equipment and digital video signal.
FPU is produced for visible and near IR ranges, provides higher accuracy and interference protection of optoelectronic devices for astroorientation and angular instruments of spacecrafts, advanced detection range in enhanced radiation and ultra-wideband electromagnetic exposure conditions of electronic countermeasures equipment.
CCDs have sections of accumulation and storage.
– spacecrafts of for various purposes;
– robotics and vision systems.
