Paper Abstract

A nondestructive laser profiler based on optical scanning method using a commercial compact laser triangulation displacement probe is described to measure the profile of the pipe inner wall surface. According to the optical feature of measured pipe inner wall surface, the adjusting posture method of laser triangulation displacement probe is put forward to reduce the disturbance and increase the measuring accuracy. the experiments are given. The method of the wavelet transform to analyze the measure results is used. The resolution of the nondestructive laser profiler is 30 micrometers .
