Abstract
PURPOSE: To enable the transmission of a bright and sharp image by providing a black coating layer on the outside circumference of a piece of specific plastic multiple optical fibers, using said fiber as an image transmission part, disposing ≥4 pieces of specific optical fibers uniformly on the outside circumference thereof, using said fibers as a light transmission part and providing a protective layer on the outside circumference thereof.
CONSTITUTION: The positions of the island parts of the core-sleeve structure having an approximately circular section, 5W200μ diameter and a light transmission characteristic and the island parts disposed at both end faces of the multiple optical fibers 1 in a 50W10,000 pieces range in the sea parts have a 1:1 relation. The black coating layer 22 is provided to the outside circumference of the optical fiber 21 for image transmission consisting of a piece of the plastic multiple optical fibers having ≥50% total area of the section in the core part within the section of the sea parts and an approximately rectangular outside circumferential shape in section and is used as the image transmission part for guiding the video from an object to be observed to an image receiving part. ≥4 pieces of the optical fibers having the approximately circular section and ≥50μ diameter are uniformly disposed on the outside circumference thereof and are used as the light transmission part. A protective layer 24 is further provided on the outside circumference thereof. The sharp and bright image is thereby obtd.
