摘　　要：本文分析并研究了用相位复共轭进行单根多模光纤传像时的光线偏振特性及其对像传输的影响.提出了检偏滤波方法,用这种方法可以十分有效地减少噪声,提高图像质量.本文给出了理论分析及实验结果,获得40linls/mm分辨率的传输图像.The polarization property of the light beam carrying an image while passing through a multimode step-index optical fiber and its effect on the quality of the image tnransmission by phase conjugation are studied in this paper. The method of filtering the noise is suggested. With this method, main part of the noise can be reduced and the image quality can be improved. Both the theoretiial analysis and esperimentat results are given, and a transmitted image with a resolution of 40 line/mm is obtained.
