Unpacked TDI PhCCD designed for large format optoelectronic systems for the Earth remote sensing

For the large format high-performance optoelectronic Earth remote sensing (ERS) system "Resource -DK" specialized PhCCD image sensor "Kruiz" meant for operation in a TDI mode was developed. PhCCD photozone size is 1024(H) x 128(V) active pixels, pixel size is 9 x 9 μm 2 . Step-by-step electronic adjustment of the PhCCD responsivity is performed by variation of the TDI stages: 128, 64, 32, 16, 8. The device has two readout shift registers and two output amplifiers and this allows to read the data from the photozone twice faster. "Electronic target" input device enables full tests of the optoelectronic converter onboard without illumination of the photozone. Unpacked chip construction allows to assemble large focal plane arrays, which's length of photozone is not limited by the PhCCD format. Here are the main characteristics of the device: full well capacity - 120 000 electrons; dynamic range - 2500; charge transfer efficiency in any direction - more then 0.99998 per transfer; maximum quantum efficiency - 0.33 (at 720 nm).
