INFRARED CAMERA AND METHOD FOR READING ALTERNATIONS IN RESPECTIVE RESISTANCE OF PASSIVE RADIATION-SENSITIVE UNITS Russian patent published in 1998 - IPC

Abstract RU 2121766 C1

FIELD: optical instruments. SUBSTANCE: device has focal-plane matrix of temperature-sensitive elements in vacuum unit with inexpensive thermoelectric temperature stabilization. Stabilization temperature is chosen by designer or by user. Preferably, stabilization temperature is expected to be room temperature. Temperature-sensitive elements are passive. Reading method involves scanning matrix by bias current shaped as short- duration high-level pulses. EFFECT: increased sensitivity. 18 cl, 6 dwg
