摘　　要：提出了海陆一体机载激光扫描仪设计方案。采用高频双波长激光以及大动态接收光路,实现地貌与水深的联合探测;采用基于自校准时间数字转换,重构高精度的点云数据;采用基于编码正交频分复用调制解调技术,实现机载点云探测数据的快速回传。The design of integrated sea-land airborne laser scanner is proposed. In order to collect simultaneous land and water-depth measurements, high frequency dual wavelength laser and large dynamic optical receiver are used. The system uses self calibrating time-to-digital converter to rebuild the high precise point cloud data. The modulation and demodulation techniques based on coded orthogonal frequency division multiplexing are used to transmit airborne point cloud data back to ground stations.
