摘要：
Laser beam automatic alignment systems are used to precisely adjust beam lines automatically in the high power laser facility. Based on a laser prototype facility requirement for aligning the cavity mirror, the edge characters of light are quantitatively analyzed by image processing the laser image in aligning cavity mirror of high power laser system. Combined with the light transfer qualitatively analysis of measurement optical system for aligning cavity mirror, the consistency of different curve edges and the circular degree of the laser images are used for quantitatively estimating the azimuth of cavity mirror. When nearly completing the cavity mirror, the circular degree of the laser image is 12.222, and the consistency of different curve edge for one page laser image is 99.62%.
