Claims (1)
る物体に向けて発射する発光素子と、一端開口部
を有し、該開口部に前記物体からの反射光のみを
通過させるフイルタが設けられた遮光箱と、該遮
光箱内に設けられて前記反射光を受光する受光素
子と、演算部とを備えた光学式測距装置において
、前記演算部は前記発光素子から発射される光信
号と前記受光素子に受光される反射光との位相差
を比較して前記発光素子と前記物体との間の距離
を演算することを特徴とする光学式測距装置。 A light shielding device that includes a light emitting element that emits a modulated optical signal of a predetermined frequency toward an object located in front, and an opening at one end, and a filter that allows only the reflected light from the object to pass through the opening. In an optical distance measuring device comprising a box, a light-receiving element provided in the light-shielding box to receive the reflected light, and a calculation section, the calculation section receives an optical signal emitted from the light-emitting element and the received light. An optical ranging device characterized in that the distance between the light emitting element and the object is calculated by comparing the phase difference between the light emitting element and the reflected light received by the element.
