| 摘 要： | 在我国沿海近岸,急需通过激光同步扫描方法建立1套浑水观测系统,解决水下视觉问题。本文研究了激光在水下的传输特性,结合散射光的分布特性,确定同步扫描的光学结构设计,通过对获得的系统各类信号特性的分析,设计合适的成像系统;并从理论和水池试验两方面分别论证了这种系统消除散射影响的有效性;论述了这种系统在浑水中的宽视角场和全景深的优良特性。

| Abstract: | A turbid water observation system using the laser synchronization scanning method is urgently needed to solve the problem of underwater vision in the coastal water.This article first researches underwater laser transmission characteristics,then presents the design of the optical structure of synchronization scanning in combination with the distribution characteristics of scattered laser.An appropriate imaging system is designed by analysing all kinds of signals obtained.The system can be widely used in ocean engineering as it has effectively eliminated the influence of backscattering,and is of wide visional angel and full depth of field in turbid water. |
