DYNAMICALLY-ACTIVATED OPTICAL INSTRUMENT FOR PRODUCING CONTROL SIGNALS

摘要

An optical controller for providing control signals, emits radiation to laterally spread through a discrete volume of space above a single source of radiation. A sensor through a discrete volume of space above a single source of radiation. sensor receives radiation from the single source as reflected from an object that is positioned within the volume of space to provide a sensor signal. A relative position of the object from the sensor signal is determined, and a control signal representative of the object is provided.
