Abstract
Control systems and methods for aligning multimode optical fibers are provided. A method includes producing a brightness profile for a first and second multimode optical fiber. The method further includes determining a cladding center position and a core center position from the brightness profile of the first multimode optical fiber and from the brightness profile of the second multimode optical fiber. The method further includes calculating a concentricity error for the first multimode optical fiber based on the cladding center position and the core center position from the brightness profile of the first multimode optical fiber and for the second multimode optical fiber based on the cladding center position and the core center position from the brightness profile of the second multimode optical fiber. The method further includes aligning the first multimode optical fiber and the second multimode optical fiber based on the concentricity errors of the first multimode optical fiber and second multimode optical fiber.
