Title: Measuring method of amount of eccentricity between core and clad of optical fiber and direction of eccentricity
Inventor: KOIZUMI FUMITO
IPC: G01M11/00
Filed: 1987-07-21
Abstract: PURPOSE:To enable the measurement of the amount of eccentricity between the core and the clad of an optical fiber and the direction of eccentricity, by a method wherein a uniform parallel light having a larger width than the diameter of the optical fiber is applied to the lateral side of the optical fiber from a plurality of directions being three or more. CONSTITUTION:When a laser whose beam diameter is larger than the diameter of an optical fiber 21 is applied to the lateral side of the fiber 21, the intensity pattern of a back scattering light is formed on a screen 23. This pattern is taken in a frame memory 27 by a one- dimensional image sensor camera 24 and subjected to a processing of a CPU 27 to determine a scattering angle between the innermost peaks holding the point O (the center of the optical fiber) of the scattering angle of the aforesaid pattern between, and the angle thus determined is held in a CPU 28. Next, a rotary pulse stage 25 is rotated at a prescribed angle and the rotation is continued until the laser light circulates at one time around the fiber 21. Then a plurality of scattering angles between the innermost peaks holding the point 0 of the scattering angle of the aforesaid pattern are held in the CPU 28. The same direction with that of the application of the laser light giving the maximum value of said angles is assumed to be the direction of eccentricity of the optical fiber, and further the amount of eccentricity is obtained from the ratio between the maximum and minimum values by using an experimental formula of the CPU 28.
