【Abstract】 Anew stylus measuring system for curved topography is described. Laser-grating inter-ference is introduced into the stylus contour graph.Areflective cylindrical hologram diffu-sion (RCHD) grating is used as a standard device to obtain a wide dynamic range and inter-ferometric fringes with microcomputer division are used to give a high resolution. The newstylus system developed is capable of measuring curved surface topography and analyzing ac-curately all kinds of characteristicsprinciples,photoelectric signal processing,hardware andsoftware design and mathematical model of curved surface topography are discussed.Experi-mental results of typical curved surface topography. are given.更多还原
