Abstract

x1÷11 μm optical code sensor with Gray Code system based on miniaturized Photoconductive Mercury-Cadmium Telluride / Hg_1-xCd_xTe (PC MCT) detector with three-stage thermoelectric cooler (TEC) has been developed and fabricated. Performance of PC MCT detector is presented evidencing good detectivity D* and responsivity R_V values in spectral range from, 1,0 to 10,6μm. Sensitive area structure allows producing of four digits Gray Code. Sensor can be used in electro-optical systems for spatial recognition of powerful sources of coherent infrared radiation.
