Filed: 1986-02-28
Abstract: PURPOSE:To enable highly accurate measurement within a short time, by performing a specific operation using the length of a light path from the end surface of an optical fiber to the position on an image pickup means to measure the angle of the end surface of the optical fiber. CONSTITUTION:When the axis of optical fiber 1 to be measured in the longitudinal direction is set to an x-axis and the angle formed by the end surface of the optical fiber 1 and the y-axis is set to theta, the illumination light from the illumination light source 2 placed on the x-axis passes through a half mirror 10 to irradiate the end surface of the optical fiber 1. Whereupon, reflected light 4 returns at the angle 2theta with respect to the x-axis. The reflected light 4 is partially reflected by the half mirror 10 to reach the image pickup element 5 placed on an x'-axis parallel to the x-axis and projected to a position P1. The image forming position P1 of light is detected and, when the angle of the end surface of the optical fiber 1 is 0 deg., the distance between position P0 where the light reflected on an image pickup means is formed into an image is measured by image processing and the operation of formula is performed using the length L0 of the light path from the end surface of the optical fiber to the position P0 on the image pickup means to measure the angle theta of the end surface of the optical fiber.

Filed: 1996-02-05
Abstract: PROBLEM TO BE SOLVED: To suppress the difference in the strength of a spot on an imaging surface by the dependence on polarization of the respective optical elements of an imaging optical system on which the luminous fluxes emitted from the optical fibers are made incident by changing the attitudes of the plural optical fibers for leading the luminous fluxes from plural semiconductor lasers and adjusting the errors of the polarization states of the respective exit light rays from a reference state so as to be kept within a prescribed permissible range. SOLUTION: A polarizer 400 rotatable around the central axis of the optical fiber 121 and a power meter 410 for detecting the light quantity of the luminous flux transmitted through the polarizer 400 are arranged on the exit side of the optical fiber. While the polarizer 400 is rotated at the time of adjustment, the transmitted light quantity is measured and the polarization state of the exit light is judged. The change in the output of the power meter 110 from the rotating angle of the transmission axis of the polarizer 400 is decided to enter the permissible range when this change is kept within the prescribed range. If the change does not enter the permissible range, the attitude of the optical fiber is so adjusted that the polarization state of the laser beam emitted therefrom approximates the prescribed reference state.
