Abstract
According to an aspect, a detection device includes: a light source configured to emit light; a planar optical sensor on which a plurality of optical sensors configured to detect the light from the light source are two-dimensionally arranged; an object placement member on which an object to be detected is placed between the light source and the planar optical sensor; a light controller that is provided between the object placement member and the light source and is configured to diffuse the light from the light source; and an optical member that is provided between the object placement member and the planar optical sensor and configured to limit light reaching the optical sensors.
