酸溶法光纤传像束透光性能的研究

为了解决酸溶法光纤传像束光透过率较低(不足40%)的问题,通过在传像束的两个端面加镀增透膜,其透过率有了明显的提高,达到了7.38%,拓宽了传像束的应用领域。介绍了膜系设计、镀膜材料的选择以及真空速率的控制对镀膜效果的影响。对影响酸溶法光纤传像束透光性能的各种主要因素进行了分析。

Reasearch on the improvement of the acid-leaching optical fiber image-bundles trasmission property

In order to solve the problem of the acid-leaching optical fiber image-bundles low penetration ratio (no more than 40%), the penetration ratio is enhanced by plating reflection reducing coating on both terminal faces of the optical fiber image bundle, the penetration ratio is enhanced form 4.73%to 7.38%,and thus the application fields of the image bundle is expended. The important factors to affect the platting result are introduced. These factors include the design of plating film,the selection of plating material and the control of evacuating rate. The various important factors that affect the acid-leaching optical fiber image bundles trasmission properties are analyzed and the effective solving methods are offerred.
