摘要
通过对激光测深仪的激光海面入射点分布的研究 ,得到了其疏密程度与扫描方式、扫描电机转速、激光器重复频率和飞机飞行速度等参量之间的关系 ,并对激光海面入射点分布进行了优化设计。提出使用调整激光器触发信号的码盘脉冲校正海面激光入射点分布不均匀的方法 ,并且讨论了实际的测量点的位置坐标与激光海面入射点位置坐标的确定。
To research into the distribution of laser spot on the sea surface of airborne laser bathymetric system, to obtain the relationship between its spacing and scan mode, scan driver rate, laser frequency and plane speed, and to optimize its distribution are important. The calibration method of its asymmetry distribution is put forward, and the relationship between real metrical position and laser spot position is discussed in this paper.
