摘要
为了提高分幅相机的像面一致性, 从分孔径和分振幅两种分幅方法的原理出发, 分析了物体辐射特性影响像面一致性的原因.基于光纤传像器件匀光作用, 提出了一种提高像面一致性的方法, 并以棱锥分孔径实现六分幅为例, 在LightTools软件中仿真了光纤面板厚度、纤芯直径、光线入射角度等参量对像面一致性的影响.结果表明, 当光束主光线在光纤前端的入射角在±15°内变化时, 增大光纤面板厚度或减小纤芯直径, 可使得六幅像面能量差小于0.3%.基于光纤传像器件的棱锥分幅结构, 可有效提高分幅相机的像面一致性.
Abstract
In order to improve the image consistency, the factors influencing the image consistency was analyzed according to the principle of aperture-divided and amplitude divided method. In addition, one approach for improving the image consistency based on the fiber optics imaging was presented. Taking the six-frame divided by the pyramid as an example, the influences of the thickness, core diameter of fiber face plate and incident angle on image consistency were simulated by Lighttools. The results show that energy difference of the six image planes could be less than 0.3% with increasing of the thickness or decreasing of the core diameter of the fiber, when the incident angle ranges from 15 ° to -15 °.Based on the fiber optics imaging, the optical frame-divided structure by the pyramid can effectively improve the image consistency of framing camera.
