Its optical system consists of an emitting system  receiving system  and two penta-prisms. Emitting system has three parts: a light source  beamsplitter  and aim slit. The receiving system includes a field lens  two separate lenses  and CCD. Using two little penta-prisms instead of a large planar mirror makes the autofocus system simple and compact. CCD was used as photoelectric converting device. A defocused signal is acquired by measuring the change of the two slit self-images position imaged on the CCD. A simple and compact construction of the auto-focusing system was proposed. The algorithm to calculate the moving of the slit-self images position was analyzed in order to achieve subpixel position estimation. The results of the experiments show a 10m focusing precision. The system demonstrates high resolution  easy adjustment and high reliability.   合成孔径激光成像雷达图像重构及后处理技术研究 学位论文  OAI收割 作者:  李光远   |  收藏  |  浏览/下载：74/0  |  提交时间：2018/12/26 合成孔径激光成像雷达  Synthetic aperture laser imaging ladar  直视  Down-looking  重采样  Resampling  姿态补偿  Attitudes Compensation  惯性导航系统  Inertial Navigation System  机载  Airborne  图像重构  Image reconstruction  最优化  Optimization  自聚焦  Autofocus   衍射透镜焦斑的非迭代相干检测研究 学位论文  OAI收割 作者:  王松贤   |  收藏  |  浏览/下载：49/0  |  提交时间：2018/12/26 衍射透镜  diffractive lenses  数字全息  digital holography,  微光器件  micro-optical device,  光子筛  photon sieve,  自动对焦  autofocus
