Optical input system and method

摘要

An optical system and method are disclosed. In an exemplary embodiment, the optical input system comprises a fiber optic cable defining an axial beam path, the fiber optic cable configured to reversibly deform at a bend location; an optical source coupled to the fiber optic cable and configured to inject an optic signal along the axial beam path; a detector coupled to the fiber optic cable and configured to receive a reflected signal from the fiber optic cable, the detector further configured to generate a distance parameter corresponding to the origin of the reflected signal; and a signal decoder configured to select a first input code from a plurality of input codes, the first input code corresponding to the distance parameter.
