水下成像镜头的光学设计

水下光学成像技术,如水下摄影、水下电视、水下激光距离选通成像系统等,是海洋研究与开发的得力工具,但由于水对光的散射和吸收等特殊的光学特性,以及使用环境的特殊性,使水下光学成像系统的设计和研制较陆上光学系统有更大的难度。本文指出了主要的技术关键,及设计与使用水下光学成像系统时需注意的问题,最后给出了水下电视光学成像系统设计研制的实例。

Optical Design of the Lens for Unerwater Imaging System

The underwater imaging systems such as underwater camera,video camera,and rang gated system with laser used in water are improtant tools for ocean researching.But the water has very special property for the light in it,such as scattering and attenuating.The circumstance where underwater imaging systems are being used is also very different form in the air.So it is much more difficult to design the lenses used in water compared with on land.To work properly,the lenses of the underwater imaging systems must be designed specially.This paper is main about the design of the lenses of the underwater imaging systems.All the improtant points for designing the lenses of underwater imaging system are mentioned,and an example is given in the last of the paper.
