Description

Technical field [0001] The invention relates to the technical field of optical fiber processing, in particular to a tapered optical fiber automatic polishing equipment and polishing method. Background technique [0002] At present, the manufacturing method of tapered optical fiber generally uses methods such as fusion tapering, mechanical polishing, laser cutting to change the optical fiber in the axial direction to form a tapered area to realize optical coupling, optical sensing, optical fiber sensing, and optical fiber devices. And applications in other research fields. The fusion tapering and laser cutting processes have low processing qualification rates, poor product consistency, and secondary melting has an impact on the structure of the optical fiber. Compared with the first two processing techniques, mechanical polishing has the advantages of controllable processing size and processing accuracy, and the processing process has no effect on the structure of the optical fib...
