  • Electro-optic sensor
    Patent number: 7463364
    Abstract: A sensor comprises an optical modulator that generates a modulation signal, an interferometer that mixes an acoustic signal evoked by a pulsed laser with the modulation signal to down-convert the acoustic signal to lower frequencies, and a photodetector that detects the down-converted signal.
