Abstract:
An alignment computer program for aligning an end of an optical fiber with an input of an optical waveguide of an optical device, the program being embodied on a computer readable medium, the program comprising:an alignment routine for processing electrical signals produced by a single optical sensor that have been converted into digital signals by an analog-to-digital converter to determine whether or not the end of the optical fiber is aligned with the input of the optical waveguide, wherein the alignment routine comprises: a first code segment for analyzing the digital signals corresponding to electrical signals output from a single optical sensor when light from an output of the optical waveguide is focused by a lens onto the single optical sensor the first code segment analyzing the digital signals to determine whether the end of the optical fiber is aligned with the input of the optical waveguide; a second code segment for generating feedback signals in accordance with the determination made by the first code segment; and a third code segment for causing the feedback signals to be sent to a motion control system that controls the motion and positioning of the end of the optical fiber.
