Title:
METHOD FOR CONFIRMING ALIGNMENT AND NUMBER OF COATED OPTICAL FIBERS IN IMAGE PROCESSING OF COATED OPTICAL FIBER
Document Type and Number:
Japanese Patent JP3078913
Kind Code:
B2
Abstract:
PURPOSE: To speedily and accurately confirm the alignment and the number of bare optical fibers to be connected by image processing when the coated optical fibers are connected by fusion splicing.
CONSTITUTION: An image pickup camera 10 is provided above the bare optical fibers 5 to be connected by fusion splicing and the coated optical fibers 4a and 4b are moved and aligned so that the right and left parts of an image plane picked up by the image pickup camera 10 are equal in brightness on scanning lines crossing the bare optical fibers. Further, the brightness of the overall length of the scanning lines is found in the right half part and lower half part of the image pickup image plane and used to confirm the number of the bare optical fibers 5 from reference data on the previously given number of coated optical fibers and brightness.
