遥感新技术——激光扫描三维成象系统

A New Technique of Remote Sensing——Laser Scanning 3—D Image System

激光扫描三维成象系统是一种高效率、高分辨率地获取地面三维信息的高空航空遥感新装置,它由高重复频率、高峰值功率,窄脉宽的激光光源,高精度光机扫描系统及快速大容量的数据处理系统三部分组成。

The laser scanning 3-D image system is a new airborne remote sensing device which obtained 3-D information of the ground with high efficency and high resolution. It is composed of three parts(a) A laser light source which has high repeated frequency, high peak value power, and narrow pulse width(b) A high speed, high capacity data processing system, In this thesis, the principle and overall design of this system is mainly described.
