INFRARED-RAY IMAGE PICKUP DEVICE

摘要: PURPOSE:To scan alternately and instantaneously a wide visual field narrow by providing two kinds of image forming optical systems for field, scanning the fields changing angle surface mirror. CONSTITUTION:An infrared ray which is radiated from area 1 stopped down an afocal system 3 goes to parallel luminous flux, made incident on mirror 4. The flux reflected 5 4, passes through use 7 detecting element array 9. Next, 2 6 8 9, signal 9 amplified pre-amplifier 11 main amplifier 12, thereafter, sent multiplexer 14, controlling circuit 15 together with driving part 13, discriminates wide/narrow fields, controls display area, etc., displayed CRT 17 16.
