水下电视系统研制中的技术难点及解决方法

THE KEY POINTS OF DESIGNING UNDERWATER TV CAMERA SYSTEM

水下电视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，使光学成象方法在水下环境中的使用受到了限制，同时由于使用环境的特殊性，使水下电视系统的设计和研制较陆上电视系统有更大的难度．本文指出了主要的技术关键及设计与使用水下电视系统时需注意的问题，最后给出了水下电视系统研制的实例．

Underwater TV camera is an important tool for ocean researching.But its performance is seriously influenced by the optical property of water,such as scattering and absorptivity.To work underwater properly,the camera must be strong enough to bear the high water pressure.So it is more difficult to design a system for working underwater than working on land.In this paper,all the important points for designing an underwater TV camera are mentioned,and an example is given in the last of the paper.
