| 摘 要： | 设计了一种新颖的高灵敏度和高精度星间跟踪系统方案,该方案中的关键是利用具有线性电光效应的LiNbO3晶体使入射光束产生圆锥形扫描,然后采用相干检测方法确定该光束的空间方位,据此调整细瞄准镜,实现星间跟踪.

| Abstract: | A novel inter-satellite tracking system with high sensitivity and precision has been developed. The key feature of the system is the incident beam conical scan caused by LiNbO 3 crystals with linear electro-optic effect. The incident beam direction can be estimated by coherent detection. These estimates are fed back to control fine pointing mirror for inter-satellite tracking. |
