Mid- and far-IR focal plane arrays based on Hg(1-x)Cd(x)Tephotodiodes

摘要

This review presents the results of the research and development work carried out at the ORION RD&P Center (Federal State Unitary Enterprise) on HgCdTe photodiodes and focal plane arrays based on solid solutions of mercury and cadmium tellurides for the 3-5 and 8-12 mu m spectral ranges. The structure, topology, and parameters of the photodiodes and staring and time-delay-integration focal plane arrays, as well as the structure and circuitry of silicon multiplexers developed for the focal plane arrays, are discussed. The parameters of photodiode arrays of various formats and of a prototype thermal imager based on a 128 x 128 staring focal plane array are presented. (c) 2005 Pleiades Publishing, Inc.
