Abstract

The conventional method of alignment for the laser launching system is complicated and low precision, because the system contains several optical channels and interlaced dimensions. In the high-energy laser launching system, the laser has the very high energy and abnormal wavelength in addition. That is, the alignment method is limited to cases of human safety due to the personnel involved and the higher accuracy for the lager multipler. In this paper, we prose a new method based on the auto-collimation method to solve the questions of human safety and high accuracy. In this method, we built a novel optical model used assistant optical path. To verify this method, simulations and experiment are performed. In the end, the precision impression and error compound of the laser launching system are analyzed and compared. The analysis results show that the aiming precision can reach 10” without human in the light path, which is only 1’ when using the conventional method.
