A position detection sensor that detects the relative position of a goniometer to an object to be measured when adjusting the beam irradiation position, and includes one light emitting optical fiber and a plurality of light emitting optical fibers arranged around the light emitting optical fiber. An optical fiber bundle consisting of a light-receiving optical fiber and a light-receiving optical fiber is attached to the head of the goniometer, pointing toward the object to be measured, and visible light is emitted through the light-emitting optical fiber to a reflector placed on the surface of the object to be measured. In this state, the relative distance and inclination of the goniometer with respect to the surface of the object to be measured are detected based on the amount of reflected light incident on each light-receiving optical fiber and the difference in intensity of the amount of received light between each optical fiber. A sensor for detecting the position of a goniometer, characterized by the following configuration:
