摘　　要：通过对自适应消噪技术理论分析和实验研究，成功地将其应用于旋光准直仪中。用自适应消噪技术对远近距离多种不同准直测量的实验结果进行处理，结果表明：在不同实验条件下，消噪后补偿度达３０％～８０％。The theory and methods of adaptive noise cancelling (ANC) technique are discussed briefly. By the theoretical analysis and experimental studies, the ANC technique has been applied to the laser collimator based on optical rotation successfully.The experimental results of various alignment measurements for long and short distance are processed by ANC technique, and it shows that the compensation effect after filtering under different conditions is 30% to 80%.
