Abstract
A device and method include a broadband light source in communication with a waveguide to provide a light signal for interrogating each of a plurality for sensors within the waveguide. An analyzer modulates the light signal with a microwave signal and demodulates and evaluates light signals reflected by the sensors. An amplitude and a phase of each reflected signal from each sensor is distinguished in the time domain and the modulated signal is reconstructed in the frequency domain.
