The laser measuring system for pipe inner wall inspection based on the ring optical cutting method has been developed. The measuring system consists of a laser diode, an optical ring pattern generator and a CCD camera. The optical ring from the optical ring pattern generator is projected onto the inner wall of the measured pipe and then is imaged on the CCD camera. The measuring system parameters according to the theory of light scattering and reflection are chosen to optimize the system. The experiment results show that the principle is correct and the techniques are realizable.
