DEVICE FOR OBSERVING JUNCTURE OF TAPE TYPE MULTICORED OPTICAL FIBER

摘要

PURPOSE:To measure the misalignment between the respective fibers of tape type multicored optical fiber tapes with good accuracy by projecting the juncture of the above-mentioned optical fibers from two directions diagonally with the tape faces and magnifying and measuring the misalignments of the respective fibers by each piece with the transmission images in the respective directions. CONSTITUTION:An operator drives a driving mechanism 7 by a motor 6 and moves a supporting member 5 toward the left or right while emitting light rays from light sources 1, 2 and observing the images from TV cameras 3, 4. All the optical fibers are then positioned successively by each piece on the visual axes of the TV cameras 3, 4. The images of the juncture in the upper right-lower right directions of the optical fibers can be observed with the TV camera 3 and the images of the juncture in the lower left-upper right directions can be observed with the TV camera 4 at this time. The measurement error of the misalignment is thereby decreased.
