FIELD: measuring technique. ^ SUBSTANCE: device comprises light emitting members mounted on the unmovable platform. The object is mounted on the movable platform, and the light emitting members form light beams on given parts of the object. The mirrors are mounted at an acute angle to the surface of the object and are optically connected with the photodetecting matrix through a lens. The output of the photodetecting matrix is connected with the input of the computing unit whose output is connected with the display. The device is additionally provided with the mirror mounted on the movable platform and emitter, mirror, and screen optically connected with the mirror and mounted within the sight of the lens that form the image of the light spot on the photometric matrix. The emitter generates a light beam with a small diverging angle and forms a small light spot on the screen. ^ EFFECT: enhanced precision. ^ 2 cl, 1 dwg |
