本发明讲光学目标跟踪系统。具体地说,是在反射激光光束的基础上,利用光学系统将目标象投影到光敏探测器上。获得指向用的控制信息取决于探测器表面上目标象的位置。与探测器表面相比较,当在其表面的清晰目标象至少小一些的时候,用使目标象模糊来增大目标图象的面积,例如,使探测器平面移动,离开光学系统的象平面,就能增大目标象的面积。
The present invention relates to optical target tracking system. Specifically, on the basis of reflecting the laser beam, an optical system is used to project the target image onto the photosensitive detector. The control information for obtaining the pointing depends on the position of the target image on the surface of the detector. In contrast to the detector surface, the target image is blurred to increase the area of the target image, for example, by moving the detector plane away from the image plane of the optical system when the clear target image on its surface is at least a little smaller, Can increase the size of the target image.
