OPTICAL APPARATUS, ON-BOARD SYSTEM, AND MOVABLE APPARATUS

Abstract: an optical apparatus includes a light emitting unit including light emitting elements, a light receiving unit including light receiving elements, an imaging optical system, a light division unit including a reflector, and an acquisition unit that acquires distance information of an object based on a time that is required from emission of light to reception of light reflected by the object, the light from the light emitting unit is reflected by the reflector to pass through the imaging optical system to be reflected by the object, light reflected by the object passes through the imaging optical system to transmit through the reflector to be received by the light receiving unit, a first light emitting element and a first light receiving element are in a conjugate relationship via the reflector, and the light division unit suppresses light from the first light emitting element from entering the first light receiving element.
