The polishing detection method of Side-polished fiber

摘要

Micro crack and pits of Side-polished fiber (SPF) is polished by fine sand paper and by an arc discharge, and their effects are compared. When there is no light through SPF after polishing, we will find that using an arc discharge method is better than fine sand paper polishing method especially their images being compared. When light passes SPF after polishing, we will find that transmitted light of SPF by using an arc discharge method is less than the others. In conclusion, using an arc discharge method is obviously better than fine sand paper polishing method.
