In a three-dimensional laser scanning system, the measurement accuracy of the entire system is determined by the optical system. To improve the accuracy, this paper designs a three-dimensional laser scanning optical system. In order to improve the performance of scanning, to reduce the influence of stray light and the imaging geometric distortion is required, as far as possible to improve the distribution uniformity of the image illumination. In this paper, the semiconductor laser is chosen as the light source which is suitable for laser triangulation measurement. This system ensures accuracy in the first place, and obtain larger working distance later. The volume of the measuring system is reduced by introducing layout that the beam splitter and the normal are coaxial. The Scheimpflug conditions are deduced under this structure, and the experimental results of the laser triangulation optical system are analyzed finally.
