Study on High Accuracy Laser Alignment Technique

The development of laser alignment technigue and its common characteristics of the technical key points are described. Our research results in the field of high accuracy laser alignment technique are introduced. The problems of laser beam drift and the severe interference to the laser alignment by the atmospheric environment were solved with good results both theoretically and practically. The successful research accomplishments of the laser fiber alignment system, the dualfrequency laser coaxalitry measurement system and the laser alignment system based on optical activityare the representative accomplishments in the field of modem laser alignment technique and achieve the domestic and internationnal advanced level.
