Abstract

The surface polishing quality of optical fiber imaging elements directly affects the image quality of image intensifier. In this paper, optical microscope is used to analyze the optical fiber imaging elements with different surface defects. After polishing again under the same process conditions, it is found that the surface polishing defects are reduced by 70%, and the position of the remaining 30% defects remains unchanged. This phenomenon was further studied. The 30% surface defects were observed by laser confocal microscope. The morphology and composition of the defects were analyzed by SEM and EDS. the results showed that the defects were the structure defects of optical fiber in optical fiber imaging elements. In view of the above findings, the low structure defect optical fiber was prepared and the corresponding optical fiber image imaging elements were prepared. Compared with the normal optical fiber imaging elements, the specific causes of the defects and the influence mechanism were analyzed, and the improvement scheme was proposed. The conclusion of this paper has a certain guiding significance for the internal structure optimization and surface polishing quality control of optical fiber imaging elements, and provides theoretical data support.
