Abstract

PURPOSE:To make small the visual-field angle of a beam-condensing lens, increase the energy of received beams and thus improve the precision of measurement by providing rotatably a photoreceiving optical system receiving reflected beams from a surface to be measured and by making the same follow a point on the surface irradiated by laser beams. CONSTITUTION:The laser beam L emitted from a laser oscillator 5 falls into a shaft furnace 1 through the intermediary of a rotary reflecting mirror 9 driven by a rotary driving system 8 equipped with an angle encoder 7. The point A of irradiation of the laser beam L applied on the top surface 2 of the furnace falls on a photoreceiving element 12 arranged in a case body 10 through the beam-condensing lens 11. The case body 10 is driven by a driving control system 15 through the intermediary of shafts 13 and bearing 14 projected from both side surfaces of the body. The driving system 15 makes the photoreceiving optical system 6 rotate in such a manner that it follows the point A of irradiation according to a signal from the angle encoder 7. By making scanning of the top surface of the furnace with the laser beam L by using the rotary reflecting mirror 9 the profile is measured. By this constitution, the visual-field angle of the beam- condensing lens 11 is made small and the energy of received beams is increased, whereby the precision of measurement can be improved.
