Beschreibung
Zusammenfassung:	An optical apparatus includes: a light source to emit reference light; a phototransmitter optical system to project the reference light emitted from the light source onto a measurement area extending 90 degrees or more; an image sensor having an imaging surface on which an optical image is formed; and a photoreceiver optical system to form an image of reflected light on the imaging surface, the reflected light being resulting from the reference light reflected at a measurement target present in the measurement area extending 90 degrees or more. The phototransmitter optical system and the photoreceiver optical system are disposed such that at least an optical axis of the phototransmitter optical system and an optical axis of the photoreceiver optical system partially coincide with each other, and at least a portion of the phototransmitter optical system and a portion of the photoreceiver optical system constitute a common optical system unit.
