Paper Abstract

Based on signal direction laser-scanned measuring technology, a double diameters laser-scanned measuring system is presented. The system adopts laser-scanned measuring technology combining with the special spectroscopic optical systems to form double directions laser-scanning beams, and to simultaneously realize high speed and accuracy non-contact automatic measurement of the diameters of two perpendicular directions at one section of measured workpiece. In this paper, the mathematical model of the measuring system is established. The working principle and overall structure of the system are introduced. The semiconductor laser beam transferred optical system, the scanning emitting and receiving optical systems; the optoelectronic transformation electronic system and microcomputer real-time control and data processing system are discussed in detail. The possibility of the system has been verified by experiments and errors analysis.
