Abstract
A fiber optic optical transducer or encoder is described. The outputs of two detectors receiving signals from an optical multiplexer/demultiplexer arrangement are compared to determine whether a given code bit is 'on' or 'off'. When the bit is 'on' the power received by the second detector will, for example, be greater than the power received by a first detector. When the bit is 'off' the reverse is true. A simple power level comparison thus determines the logic state of each given code bit.
