OBSERVATION SYSTEM FOR OPTICAL FIBER, AND ITS METHOD USING THE SAME, SYSTEM AND METHOD FOR ALIGNING OPTICAL AXIS OF OPTICAL FIBER

摘要

PROBLEM TO BE SOLVED: To exactly perform an alignment of an optical axis based on the improved image of an optical fiber by improving the quality of the transmitted light image of the optical fiber. ;SOLUTION: A first optical fiber 3 and a second optical fiber 4 are arranged by confronting their connected end face parts 23 to each other, a light source 5 irradiating the opposite part of the connected end face parts 23 with the transmitted light in Y direction orthogonal to the optical axis (Z direction) of the first and the second optical fibers 3, 4 through the interval between optical fibers 3, 4, and an optical fiber observation device 11 provided with a television camera 9 connected to a microscope 6 and an image processing part 10 through the interval between the optical fibers 3, 4 is provided on the opposite side interposing the optical fibers 3, 4 to the light source 5. A polarizing filter 8 selectively transmitting only time P component of the transmitted light between the path of the transmitted light between the microscope 6 and the television camera 9 in the direction in which the vibration plane of P wave is orthogonal to the optical axes of the optical fibers 3, 4.;COPYRIGHT: (C)1998,JPO
