摘要
在光电跟踪系统的研制或维修过程中,常需要测量光电跟踪系统的跟踪性能。用平行光管实现了一个旋转式的光电靶标,此光电靶标可用于测试光电跟踪系统的跟踪性能,具有占用场地小的特点。测试过程中不要求光电跟踪系统和旋转式光电靶标装置的零位重合,也不要求它们严格同轴,所以测试的调校工作量小。所研制的一个旋转式光电靶标经过实验测定其靶标最大误差为8″,误差均方根值为0.8″,满足一般光电跟踪系统跟踪性能的测量要求。
The performance of Photoelectricity Trackers is usually required to be tested in the process of developing or repairing. A revolving photo-electricity target was realized based on a collimator, and it can be used to test the Photoelectricity Trackers＇ performance. The photo-elec- tricity target occupies only a small area. When testing the Photoelectrieity Trackers, their zero points and revolving axles are not required to be same with the photo-electricity target, hence the adjust work is small. The testing results show that the maxim error of the photo-electricity targetis 8＂, and the average square root error is only 0. 8＂. It is suitable for testing common Photoelectricity Trackers.
