Abstract
Systems, devices, and methods for performing remote sensing using WMA. Embodiments include modulating an interrogation signal, transmitting the interrogation signal to a remote vibrating target, and receiving, at a first port of a WMA interferometer, a reflected signal. Embodiments also include splitting, by a first beam splitter, the reflected signal into first and second portions propagating down first and second waveguides, delaying, by a delay element, a phase of the reflected signal, and spatially phase shifting the reflected signal. Embodiments may further include splitting, by a second beam splitter, the first and second portions of the reflected signal into third and fourth portions propagating down the first and second waveguides, detecting an intensity difference between a first lobe and a second lobe of the third portion of the reflected signal, and calculating a Doppler frequency based on the intensity difference.
