在近距(150m~1.5m)空间交会对接中,CCD光学成像敏感器承担测量任务,CCD像机在观测视场角内如何捕捉到目标是首要问题。研究了自聚焦透镜阵列作为合作目标匀化器的应用,简述了自聚焦透镜的成像基本原理。自聚焦透镜,作为合作目标的出光端,由于其成像的特殊性,我们研制出了自聚焦透镜阵列匀化器,解决了在0°~±30°的发散均匀性。在观测视场角内,各角度辐亮度与中心辐量度之比在10%左右,预期做到6%。目标光源辐亮度分布在0°~±30°范围内接近朗伯体。并给出了验证试验。 In the close (150m ~ 1.5m) space rendezvous and docking, CCD optical imaging sensor to undertake the measurement mission, CCD camera in the observation field of view how to capture the target is the primary problem. The application of self-focusing lens array as a target homogenizer was studied. The basic principle of self-focusing lens imaging was described. Self-focusing lens, as the cooperation of the light-emitting end of the target, because of its imaging specificity, we developed a self-focusing lens array homogenizer, to solve the divergence uniformity of 0 ° ~ ± 30 °. In the observation field of view, the angle of the radiance and the center of the radiation ratio of about 10%, is expected to be 6%. The target light source radiance distribution in the range of 0 ° ~ ± 30 ° close to Lambertian body. And gives the verification test.
