Abstract
The present invention relates to a method of aligning circular multi-core fibers, wherein the method utilized independent and individually selected cores to receive, transmit, and emit light from input devices. The present invention further relates to positioning the ends of a multi-core fiber in order to detect and determine the precise locations of individually selected core fibers.
Claims1
A method of aligning a multi-core fiber, said multi-core fiber being composed of a plurality of individual core fibers having a first and second end, the method comprising:
- providing at least one light source to the first end of the multi-core fiber, wherein the at least one light source is applied to an independently identified and selected individual core fiber from the plurality of individual core fibers;
- detecting and determining an amount of light emitted and/or a light characteristic at the second end of the independently identified and selected individual core fiber;
- and
- adjusting a position of the second end of the multi-core fiber, wherein the independently identified and selected individual core fiber is positioned to increase the amount of light and/or light characteristic to be detected at the second end of the multi-core fiber.
