Optoelectronic analog-to-digital converter

摘要

An analog to digital converter has an optical pulse source generating an optical pulse chain having a plurality of optical pulses. An optoelectronic digitizer has a first input receiving the optical pulse chain. The digitizer has a second input for receiving the analog signal to be converted. The digitizer has a plurality of digital outputs. Each of the digital outputs corresponds to a range value. An electronic encoder receives the plurality of digital outputs. The encoder has an output in a predetermined digital format.
