Abstract
An apparatus for measuring a characteristic of an object, the apparatus includes: a light projector which projects light to an object; a photosensor which senses light which has been projected by the light projector and reflected from the object; a calculator which calculates a characteristic of the object based on an output of the photosensor; an angle detector which detects respective angles of the light projector and the photosensor with respect to the object; an adjustment mechanism which adjusts the respective angles of the light projector and the photosensor; and a controller which controls the adjustment mechanism based on a detection result of the angle detector so that the light projector and the photosensor come into their respective desired angles.
