Abstract: Disclosed herewith is an optical triangulation displacement sensor using a diffraction grating. The optical triangulation displacement sensor includes a light source element, a condenser, a light-receiving element, an image formation lens, a transmission grating and a light-receiving element. The light source element generates light of certain intensity. The condenser receives the light from the light source element and transmits the light to the surface of measurement. The image formation lens receives the light reflected by the surface of measurement. The transmission grating converts the reflected light having passed through the image formation lens into a plurality of diffracted light rays. In the light-receiving element, an image is formed by the diffracted light rays incident from the transmission grating.
