Research on Micro-vibration Detecting Optical Imaging System Verification

  • 摘要: 针对高分辨率空间相机的系统特性,选用平行光管系统作为光学系统,模拟来自无穷远的特征目标.运用LIGHTTOOLS软件对光路进行模拟,确定较优的光学结构.主要通过4种试验进行研究,即相机激振抖动试验,靶标运动模拟光轴抖动试验,波前畸变测量试验,离焦测量试验.通过离线图像复原对空间相机的光学误差进行分析及补偿.试验结果表明,在未给相机施加激振的情况下,经过平行光管系统输出,相机成像出的40LP·mm-1(LP表示线对)及20LP·mm-1清晰,满足微振动成像检测试验要求.在微振动成像检测试验中,波前像差达到0.21λ(RMS<λ/4),1.28λ(PV)以及0.23λ(RMS<λ/4),1.34λ(PV)时,该平行光管系统成像均可满足复原软件处理需求,可以有效应用于微振动成像检测系统并具有验证微振动成像检测试验的能力.
