The Laser Triangulation Measuring Sensor for Accurate Displacement Measurement

Dai,Li-ming;Jiang;Tong-jun(Southeast University)  
Abstract In this paper,based on the principle of lens imaging , the rule of variationof the image position with the measured object surface as using the laser triangulationmethod for the displacement measurement is described, the relation of the incident angle oflaser with the image angle is dervied and the design method of the construction parameters ofthe laser triangulation measuring sensor is discussed.
