Abstract

Development results of photodetective assemblies for 1.5 ÷ 2.5, 3 ÷ 5 and 8 ÷ 14 micrometer spectral ranges achieved last time in RD&P Center 'Orion' are discussed. In thermal imaging and heat location systems with high space and temperature resolution photodetectors with a minimum size of sensitive elements and a maximum signal/noise ratio at the output of readout microelectronics are used. Submatrix photodetectors (MxN) operating in the time delay and integration mode (TDI) as well as 'staring' arrays (N X N) were the most extensively developed. Comparative parameters and characteristics of photodetectors with intermediate and deep cooling based on PbS (2x1536), PbSe (1x256), InSb (384x288), CdHgTe (2x256, 4x128, 128x128, 384x288) with photosensitive element sizes from 100 to 30 micrometer are given. Thermoelectric cooling or microcryogenic Stirling coolers provide operating temperatures. Development results of high-speed photodiodes based on Ge, Si and InGaAsP for optical communication and range finding in 0.8 ÷ 1.7 μm spectral range as well as CdHgTe photodiodes with high speed of up to 1 GHz for laser detection and ranging at 10.6 μm wavelength are given.
