【摘要】：采用微进多空间多焦点自由曲面镜头与成像面的设计方法,设计了卡塞格林望远镜的镜头与成像结构;建立了激光雷达镜头与成像面的微分方程,解出自由曲面光焦度变化曲线图;采用反求工程中的自由曲面重构技术,通过离散曲面的离散数值解法,获得了自由曲面的镜头与成像面三维数值,进行了自由曲面光学(FFO,free from optics)镜头与成像面离散重建;研制了海星形海底小型激光雷达系统。实验结果表明,系统整机实现了全景探测,解决了海底水域的设施与异物的探测与监测的难题。
[Abstract]:The lens and imaging structure of Cassegrin telescope is designed by using the design method of micro-entry multi-space and multi-focus free-form surface lens and image surface. The differential equation between Lidar lens and imaging plane is established, and the curve of free-form surface focusing is obtained. By using the technique of reconstruction of free-form surface in reverse engineering and the discrete numerical solution of discrete surface, the three-dimensional numerical value of lens and image surface of free-form surface is obtained, and the discrete reconstruction of free-form surface optics (FFO,free from optics) lens and image surface) is carried out. A small ocean-starlike laser radar system has been developed. The experimental results show that the whole system realizes panoramic detection and solves the difficult problem of detecting and monitoring the facilities and foreign bodies in the sea-bed waters.
