Abstract

As one of the experimental payloads on Luojia-1 satellite, the nighttime imaging camera works with a high sensitivity to acquire nighttime light on earth. Solar stray light is a fatal problem for optical satellite works in the polar orbit, even for nighttime scene imaging, resulting in image saturation and light signal detection failure. To solve this problem, an analysis of the range of solar incident angles was conducted firstly. Based on the result, a special-shaped baffle was designed to avoid direct sunlight incidence. Moreover, the capability of stray light elimination of the lens was enhanced by an order of magnitude via optimizing the internal structure. An evaluation of secondary scattering stray lights into the camera from surrounding parts was performed based on a real satellite model. The results showed that the stray light elimination reaches a 10 order, meeting design requirements. Utilizing on-orbit images, the ability of satellites in illuminated areas to obtain artificial lights in dawn-dusk area was verified, proving the effectiveness of the stray light elimination design.

摘要

作为珞珈一号卫星的实验有效载荷之一，该型夜光成像相机具备高灵敏度，可在夜间对地球夜光进行观测。杂光问题是极轨卫星观测的致命问题，即使在夜间观测时，仍会导致图像饱和，使光信号探测失效。为解决该问题，首先对太阳入射角度范围进行了分析。基于分析结果，设计了一种特殊形状的遮光罩，以避免直接阳光入射。此外，通过优化内部结构，将镜头的杂光消除能力提高了一个数量级。基于真实卫星模型，对来自周围部件的二次散射杂光进入相机的情况进行了评估。结果表明，杂光消除达到 10 个数量级，满足设计要求。利用在轨图像，验证了卫星在光照区域获取晨昏区域人工光源的能力，证明了杂光消除设计的有效性。
