Abstract:
PCT No. PCT/DE97/02851 Sec. 371 Date Jun. 7, 1999 Sec. 102(e) Date Jun. 7, 1999 PCT Filed Dec. 5, 1997 PCT Pub. No. WO98/25171 PCT Pub. Date Jun. 11, 1998A system and method for simultaneous representation of a surface profile of any given object, specially to measure the surface profile of teeth, comprises a light source to illuminate the object, an optical element to focus the light signals returning from the surface of the object, a detector to pick up the light signals, and a processor that digitizes and further processes the detected signals. The method enables quick, reproducible scanning of the surface profile by using as few devices as possible while ensuring at the same time a viable constructive size. The method includes placing a beam output coupler in the beam detection path downstream from the optical element to simultaneously couple our the light returning from the various image planes, the coupled-out light being guided to the detector.
