Infrared radiation detector, has sensor arrays housed in case, including infrared radiation detection unit and detecting incident beam transmitted from different incidence direction by slits of case

摘要

The detector (100) has a case (40) including slits for transmitting infrared rays. A group of sensor arrays (10t 1, 10t 2) includes an infrared radiation detection unit for detecting infrared radiation from the case, where the sensor arrays are housed in the case. Each sensor array detects an incident beam transmitted from different incidence direction by the slits of the case.
