Information Processing Technology Of Three-Dimensional Measurement System Based On Phase Laser

With the rapid development of industry technology, measurement technology based on laser is more and more widely used.The traditional measurement methods and instruments are unable to meet the growing demand of science and economy, so instruments with the ability of high precision、automation、fast measurement have become an important research direction.This paper introduces the detail of current development at home and abroad on the base of data from all over the world. Describes the basic principle of three-dimensional measurement based on laser. Its research contents include high frequency modulation technology in infrared laser、digital processing technology and smart tracking technology based on laser beam. We use DSP TMS320F5402to design the signal processing circuit and at the same time we complete the hardware design of receiving system.The experimental results show that the research technology above can both improve the measurement speed and guarantee measurement precision in three-dimensional large size measurement and improve automation degree of all measurement system.
