Paper Abstract

Tapered optical fibers are created by stretching of the optical fiber so that their diameter at the narrowest area is only few microns. In this form, they are very interesting for optical sensor applications. The developed vision sensor for a filament positioning is a key element of the optical fiber tapering system. It allows controlling the speed of stretching the fiber what significantly reduces the chance of its breaking. The paper presents the sensor developed based on a fixed-focus camera equipped with a wide-angle lens and using image processing and analysis techniques. Determining the position of a filament consists in determining the angle of its deviation from the reference position. The required stretching speed of the fiber is determined based on the determined angle. In the paper, the way of carrying out measurements of position of optical fiber using the sensor and the results obtained were presented.
