Title:
DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/226021
Kind Code:
A1
Abstract:
A detection device has: an optical sensor including a sensor substrate, and a plurality of photoelectric conversion devices that are mounted on the sensor substrate and output signals corresponding to light applied to the photoelectric conversion devices, respectively; a light emitting device for applying emitted light in a direction toward an object to be measured; and an optical device that includes a plurality of first light-transmitting regions and a non-light-transmitting region, and is provided between the optical sensor and the object to be measured. In the optical device, the plurality of first light-transmitting regions are provided at locations aligned with the plurality of photoelectric conversion devices, respectively, to penetrate the optical device in the thickness direction, and allow incident light incident on the photoelectric conversion devices to pass through. The non-light-transmitting region is provided between the plurality of first light-transmitting regions, and has lower light transmittance than in the first light-transmitting regions.
