Abstract : The patent describes a radiation detector which operates in the infrared 1 to 14 micrometer region of the electromagnetic spectrum. The device consists of an array of charge coupled elements controlled by capacitive coupling through the oxide layer of the semiconductor substrate by a photoconductive resistor. The photoconductive resistor changes the voltage on the gate of the charge coupled element upon detection of infrared light to open a channel for minority carriers to flow from the source to the drain of the charge coupled element. The drains of the array are subsequently connected to form a shift register so that the image information may be retrieved.
