Title: INFRARED SENSOR
Abstract:
The present invention addresses the problem of providing an infrared sensor with which it is possible to suppress variation in sensitivity within a detection area. One small detection area (13) among a plurality of small detection areas (13) is associated with each of a plurality of first lenses (50a) of a first light-receiving unit (2a), and one small detection area (13) among the plurality of small detection areas (13) is associated with each of a plurality of second lenses (50b) of each of a plurality of second light-receiving units (2b). The optical axis of a second light-receiving element (30b) of each of the plurality of second light-receiving units (2b) is inclined, in a mutually different orientation, with respect to the optical axis of a first light-receiving element (30a) of the first light-receiving unit (2a). The number of a first group of small detection areas (13) associated with the first light-receiving unit (2a) from among the plurality of small detection areas (13) is greater than the number of a second group of small detection areas (13) associated with each of the plurality of second light-receiving units (2b) from among the plurality of small detection areas (13).
