Apparatus and method for efficient two-way optical communication where transmitter may interfere with receiver

摘要: An two-way optical communication apparatus, including a transmit element, receive and transceive processor. The element is coupled to light pipe, transmits first signal. the receives second processor directs pause then resume transmitting signal during intervals, sample for one or more intervals within each of where less than value occur at duty cycle no greater value, values are controlled by such that user perceives as having constant state third interval.
