Photoelectric automeasurement system for shape and position

摘要

Abstract: This paper discusses a main unit of photoelectric automeasurement system for shape and position which is composed of slit scanning optical system with semiconductor laser and fine servo mechanical system. A single chip micro- computer, real-time data processor and other hardware are used to form a main controller to realize high sped, non- contact auto-measuring roundness, cylindricity, axiality and parallelism for revolving part C language is used to program for software. The computer is used for real-time data processing and controlling, displaying measuring result and printing output. Whole work of the system is done accurately and automatically with high speed. So it has good future in production. !0
