Abstract: PURPOSE: A device detects optimally infrared rays radiated from the earth to provide a relative coordinate for observing a specific area or earth environment by considering mechanical characteristics of a chopper without a satellite motor in the conventional device. CONSTITUTION: A device has a gold coated mirror(10), a lens(20), a drive coil(30), a chopper(40), a detector(50), a band pass filter(60), a multiplexer(70), a gain controller(80), and an AD converter(90). The mirror(10) reflects the infrared rays, which passes a slit in the chopper(40) through the lens(20). The chopper(40) forms discrete signals based on the input infrared rays, the band pass filter(60) eliminating unnecessary components of the signals and the multiplexer(70) sequentially selects the signals from each cell of the detector(50) to pass them to an amplifier(81). The gain controller(80) adjusts an amplification ratio of the amplifier(81) according to external conditions. A chopper driver(41) controls an angle of the chopper(40) to enhance the detection capability of the detector(50).
