Abstract
Anew type of optical range sensing method suitable for surface tracing ( RORST : Riken Optical Range Sensing Method for Surface Tracing ) has been developped. An axial symmetrical cylindrical or circular conical ) light sheet is projected on to an object; a ring pattern is produced on the surface of an object; the ring pattern image is projected on to an observation plane by an objective lens; radii of the ring pattern image on the observation plane for different azimuths are detected; distances corresponding to the specified azimuths are determined by the principle of triangulation; thus the information of partial inclination can be obtained. Basic experiments have been perfomed and it has been proved that the proposed method can provide a compact optical range sensor which can detect not only the distance but also the partial inclination of a surface.
