| 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. |
