Abstract
An optical device includes: a light guide body that scatters light incident from an end surface with a scatterer disposed in a direction in which a side surface extends and emits the light; a mirror surface reflecting plate that mirror-reflects the light emitted from the light guide body; a light receiving unit that receives the light reflected by the mirror surface reflecting plate; and a diffusion plate that diffuses and transmits the light emitted from the light guide body and emits the light onto the mirror surface reflecting plate, and diffuses and transmits the light reflected by the mirror surface reflecting plate and emits the light to the light receiving unit.
