Patent US 3,970,990

An adaptive imaging system is described incorporating: a two-dimensional electro-optical detector array with as many as one hundred million detectors; a time-sharing multiplexer which samples each preamplified detector signal; an A/D converter and digital filter; and a computer which generates adaptive control signals to the rest of the system according to criteria observed and recognized by the system. Coupling conductors between detectors and their respective amplifiers are three-dimensionally packaged on multilayered modules. An algorithm, incorporating coincidence logic, for directing and controlling the data processing of the system is described.
