摘要： Gambling等[1]提出通过测量单模光纤远场辐射图,可以确定单模光纤的归一化频率V,纤芯直径2a,相对折射率差 △三个主要参数.远场法是通过一个实验能同时解决三个参数测量的好方法.

Abstract: This paper describes measurement of single mode fiber parameters by observation of far-field radiation pattern which is received by a vidicon and displayed on a monitor, while light intensity distribution of the far-field pattern is obtained by selected singleline scanning. V-value is determined directly by the ratio of sin θ0 and sinθ0.5 from the light intensity distribution. Typical experimental results are given.
