| 摘 要： | 天顶跟踪盲区是地平式光电跟踪系统的固有缺陷。X-Y双轴式光电跟踪系统（规则X-Y双轴式）可以解决过顶跟踪问题，但跟踪范围极为有限，把视轴沿X轴方向平移偏距D，形成一种改进的X-Y双轴式光电跟踪系统，即偏X-Y双轴式光电跟踪系统。偏X-Y双轴式光电跟踪系统可以解决过顶跟踪问题，其跟踪范围与规则X-Y双轴式光电跟踪系统相比有很大提高。由D引入的跟踪误差可以忽略或修正，但具有更大的地平面跟踪盲区。

| Abstract: | Photoelectric tracking system with horizontal gimbal can not track objects near zenith. However, photoelectric tracking system with regular X-Y double-axis gimbal can track the object at the zenith, but it has small tracking region. X-Y double-axis gimbal by X axis transferring D could track objects near zenith, has wider tracking region than regular X-Y double-axis gimbal. Tracking errors because of D could be ignored or corrected, but has bigger blind region on the horizon than regular X-Y double-axis gimbal. |
