| Abstract: | Semiconductor laser and linear CCD are the key components for collimator. The drift of semicorductor laser is one of the factors influencing measurement precision. A method adopting double laser beam incorporation compensation and flat mirror reflection is proposed. This method shortens the propagation distance of laser beam and reduces the influence of atmospheric disturbance on laser drift. The experimental result shows that the precision of the laser collimator has been increased by 50 percent. |
