Abstract
A transducer for optical data transmission is disclosed in which an optical signal is encoded with information representative of a parameter being measured and transmitted to a remote measurement and control apparatus site for decoding. An input optical signal is received by the transducer and separated into first and second portions. The first portion of the optical input signal is converted to electrical energy and is used to power the transducer. The second portion of the input optical signal is modulated in response to the measured parameter and the modulated signal transmitted back to the remote site.
