卫星激光测距仪发散角系统的设计

介绍了房山人卫站近期对人卫激光测距仪发散角系统改造和完善过程中所开展的一些工作。首先针对实际工作中不同高度的观测卫星,按照光学原理设计了一套由成像系统、传动系统以及控制系统组成的自动调整发散角的装置,通过调控力矩电机的电压,经联轴件带动丝杠旋转,使滑块前后移动,从而改变成像系统,使激光束的发散角产生变化。其次为了验证系统设计的合理性,对本套装置进行了相关的实验。从实际的观测情况可以看出,改造后的发散角调整系统在提高整机观测能力方面有明显作用。

Laser divergence designing for satellite laser ranging

Some reconstructing and improvements of the laser beam expander in satellite laser ranging system of Beijing SLR station were developed recently.Firstly a set of light beam auto-control expander including imaging system,driver and controller was designed according to optical theory for different height of satellites.The laser divergence change was made by transformation of voltage of the moment motors with the connectors making the screw running and sliding block moving.So the whole imaging system was influenced.Meantime some tests were made to the equipment for validating rationality of the design.The result of tests was very satisfactory in enhancing the ability of ranging for the whole SLR system.
