Paper Abstract

This rir puts forward a method of laser ubIe trigonorrtrical nasurerrnt of 3-D (three dirrnsional) curvd surfaces,the taret light spots form images on two photoelcvtrio receptrs CCDs (Charge Coup1txi Device) separately through two setc of image-forming system. The plane ccrdinates of the liRht spots ran ained from the irriging pSitt)nS of the spot on CCDs. Then we can measure a curve by rotating a faceted lens to achieve spot scanning in the end when the nunrically controlled vrktable brings along the nasuring table to revolve, we can measure a curved surfaceS
