  • RF-photonic system for acoustic and/or vibrational sensing using optical fiber and method thereof
    Patent number: 10031246
    Abstract: A method and system comprising: an optoelectronic oscillator comprising a light generator, a modulator, and at least one optical fiber, the optoelectronic oscillator operating to send a modulated carrier signal through the optical fiber into a target area and receive the return signal; a circuit for removal of the carrier frequency operatively connected to the oscillator comprising at least one phase shifter; at least one mixer operatively connected to the at least one phase shifter; at least control circuit operatively connected the at least one mixer and the at least one phase shifter for controlling the phase shifter and operating to cancel signals other than the sideband signals; a signal processor for processing the sideband signals to detect acoustical and/or vibrational signals from the target area. The method comprises sensing vibrational and/or acoustical signals for detection of acoustical and/or vibrational signals in the target area.
