光透過物体で構成した光学装置。[Claims for Utility Model Registration] (1) A pair of images of an object are formed on or near a pair of optical sensor arrays, and the distance to the object is measured based on the relative position of the two images. In the optical device of the distance measuring device, (a) it has a pair of lens pieces, and both lens pieces are arranged so that the principal axes of both lens pieces do not overlap, and (b) a part of the lens piece away from the principal axis is An optical device that forms a pair of images on or in the vicinity of a photosensor array using only light that has passed through a portion of the other lens piece that is separated from the other lens piece across both principal axes. (2) An optical device using a Fresnel lens piece as a lens piece in claim (1) of the utility model registration. (3) In claims (1) and (2) for utility model registration, an optical device in which a pair of lens pieces or Fresnel lens pieces are made up of a single light-transmitting object.
