摘要
光在海水介质中传播时,由于各种因素比起在空气中传播复杂得多,因而影象光信号受到众多因素的干扰,从理论和实验两个方面分析研究表明,采用对称性照明系统是提高影象衬度的一种有效方法,我们作了对称性双光源的实验,与单光源比较影象衬度提高两倍多。
The travelling of light signal in medium of sea water is more complex than that in air,because it was interruptted by many factors。Theorical and experimental survey show that the symmetrical lighting system is an efficient method of improving the contrast of image,We have done an experiment using symmetrical double light sources,it shows that the contrast is improved by twice of single light source。
