Abstract
A method for positioning a movable reflector in an optical switch. A set of optical power values are generated by measuring optical power related to optical reflections from the movable reflection for a plurality of positions of the movable reflector. A processor is used to generate a mathematical approximation of a relationship of optical power versus reflector position based on the set of optical power values. A position of the movable reflector is chosen based on a point in the mathematical approximation of the relationship of optical power versus reflector position.
