ABSTRACT:
An optical apparatus for performing multi-point distance measurement by measuring the distance to an object using a triangulation method and light received from the object, includes first and second light-receiving systems each constituted by a multi-eye lens in which a plurality of elementary lenses are disposed adjacent to each other in a base line direction, and a photoelectric conversion element. The first and second light-receiving systems respectively form images of regions of the object, which correspond to the elementary lenses constituting the multi-eye lenses and are separated from each other, on the photoelectric conversion elements.
