1.2m激光测距系统及其噪声抑制技术

介绍了激光测距技术的过去和现状及其科学意义，系统地讨论了激光测距系统的构成及各组成部分的发展，分析了测距过程中各方面的误差来源及其相应的消除或减小误差的方法。对于目前正在调试的云南天文台１２ｍ激光测距系统作了详细的介绍，对该系统的噪声抑制技术也作了具体的讨论。

1 2m Satellite Laser Ranging System and It's Noise-restraint

In this paper, we briefly introduce the history and current status of the subject of Satellite Laser Ranging(SLR). After a brief introduction of the science application of SLR, the structure of Laser Ranging System(LRS) and the development of the components which make up the LRS are introduced. We also discuss the main sources of range error in the ranging experiment, while the ways to remove or minimize the range error are discussed. We also introduce the 1 2m LRS of Yunnan Observatory in detail which is under test now. At the last part of the article, the technology restraining noise of 1 2m LRS is introduce specifically.
