【摘要】 介绍了一种测量单模光纤剖面折射率分布和色散的新方法光学相关识别方法。应用计算全息制作高斯-拉盖尔模的匹配滤波器,根据光学相关识别原理测出单模光纤场分布的展开系数,由此推得剖面折射率分布和色散,给出了实际测量结果。

【Abstract】 Refractive index profile and modal dispersion in single mode optical fibers are computed from the measured expansion coefficients of the near field, which is expanded in a series of Gauss Laguerre functions. The coefficients of the series are measured from the correlation intensity between the near field of single mode fibers and the Gauss Laguerre mode of filter fabricated by computer generated holograms. The main advantage of the proposed method lies in its inherent insensitivity against random measurement errors and low optical dynamic range of a detector.
