摘要
介绍了一种双光束自适应准直测量系统。传感元件为两套楔角相同的左旋和右旋石英光楔。由于两束光足够靠近,用其中一束光专门监测各种漂移因素以便补偿另一束光的测量结果,从而达到对环境干扰自适应补偿的作用。文中给出了理论分析和实验结果。
A twin-beam adaptive alignment measurement system is introduced. The sensor consists of two sets of quartz wedges which are respectively right-handed and left-handed with equal angle. One of the laser beam serves as measuring beam and the other for monitoring of the environment turbulance. Because the two beams are close enough to each other, the effect of atmosphere can be compensated by this system. Theoretical and experimental results are given in this paper.
