Filed: 1987-11-25
Abstract: PURPOSE:To measure the displacement and inclination of an object body of inspection independently at the same time by constituting a photodetection optical system so that an inspection surface and the sensor surface of a position detection sensor are in image formation relation for the displacement of the object body and both surfaces are in in-focus relation for the inclination. CONSTITUTION:Light beams from a light source 1 consisting of a semiconductor laser, etc., are projected on the inspection surface of the object body 2. Regularly reflected light beams from this inspection surface are made incident on the sensor surface of the position detection sensor 4 composed of a CCD, etc., through the photodetection optical system 3 consisting of a lens 5 and a cylindrical lens 6. At this time, the optical system 3 is so constituted that the inspection surface of the object body 2 and the sensor surface of the sensor 4 are in the image formation relation for the displacement of the object body 2 and also in the in-focus relation for the inclination of the body body 2. Therefore, when the displacement is detected, there is not any influence of the inclination of the detection surface and when the inclination is detected, on the other hand, there is not any influence of the displacement of the inspection surface, so they are measured by the single measuring instrument independently at the same time.
