Abstract
An imaging device includes a reflection polarization prism having an incident surface on which illumination light emitted from a light emitter is incident and a transmission surface that passes the illumination light entered the incident surface through one surface of a light-transmitting member, an imager including an image sensor having a first light-receiving portion that receives light from a predetermined imaging area transmitting the light-transmitting member and a second light-receiving portion adjacent to the first light-receiving portion that receives the illumination light reflected on an opposite surface to the one surface of the light-transmitting member, and an optical member that emits the light introduced from the predetermined imaging area to the first light-receiving portion and emits the illumination light reflected on the opposite surface of the light-transmitting member to the second light-receiving portion.
