Abstract
In the article the light beam behavior of a long distance laser collimation is experimentally studied and theoretically analyzed. The method of multiple- point monitoring and error correction is put forward to established a highly stable collimation datum line. The multiple-point sampling measurement system controlled by a microcomputer has been designed and established. A model of correcting the light beam drift by the method of mixed multivariable variance has been gotten. The influences of the light beam drift, the light beam incurve, the light beam random tremble, and etc. are comprehensively considered in the correcting model. The correcting model can be suited to different measurement conditions. The experiment result indicates that the light beam drift corrected by the mixed multivariable variance model makes form 45% to 80% reduction under different experiment conditions.
