激光前向散射技术也能用来保证硅树脂涂复石英光纤的同心度。本文用射线光学的原理解释了散射图形的产生及其变化,介绍了同心度监视方法在随机拉丝中的应用结果。 Laser forward scattering technology can also be used to ensure the concentricity of silica-coated silica fibers. In this paper, the principle of ray optics is used to explain the generation and change of the scattering pattern. The application results of the concentricity monitoring method in the random drawing are introduced.
