Abstract: Apparatus and associated methods relate to a system for interfacing with an optically-powered sensor. The system includes an optical emitter configured to emit a beam of optical energy so as to provide operating power for the optically-powered sensor. The system includes an optical detector configured to detect a time sequence of optical pulses generated by the optically-powered sensor, the time sequence of pulses modulated between first and second optical power levels. The system includes a parameter extractor configured to determine a value of a sensed parameter based on the time sequence of optical pulses detected by the optical detector. The system also includes a power controller configured to control power level of the emitted beam of optical energy based on the first and/or second optical power levels detected by the optical detector.
