Abstract

As the special core structure of the helical-core fiber, it has high fabrication difficulty. It has a high precision of fabrication system requirement. The coaxality of optical fiber rotation is one of the key technologies. Under the premise of a helical-core fiber fabrication system designed and manufactured, this paper puts forward micro-imaging test method based on the centroid method. This method gets the image of fiber core spot through the microscopic imaging system, and calculates the energy center of the spot image by using the centroid method. Thus we get the center and radius of rotation of the spot image after the fabrication system rotated a period. Thereby the testing and adjustment of the fabrication system coaxality are realized. The experimental results show that this method can complete the coaxality testing of helical-core fiber fabrication system; make offset of the core be less than 10 μm. This method solves the disalignment problem of optical fiber rotation during the process of helical-core fiber fabrication well.
