Title:
INFRARED DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/101002
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an infrared detection device whereby unevenness of sensitivity in a sensing area can be suppressed. Each of a plurality of light receiving units (2) in a light receiving system (1) includes an infrared light receiving element (30) and a multilens (5). The multilens (5) has a plurality of lenses (50). A predetermined sensing area (11) is a synthetic sensing area of a plurality of sensing areas (12). Each of the plurality of sensing areas (12) is a synthetic small sensing area of a plurality of small sensing areas (13). Each of the plurality of lenses (50) of each of the plurality of light receiving units (2) corresponds one-to-one with a single small sensing area (13) among the plurality of small sensing areas (13). In at least two sensing areas (12) among the plurality of sensing areas (12), the small sensing areas (13) of each of two adjacent light receiving units (2) among the plurality of light receiving units (2) are intermingled.
