摘要
A method for detecting and measuring physical perturbations sensed by a multi-mode waveguide, through which a number of modes of a coherent electromagnetic wave propagates through and exit from. The method comprises irradiating the exiting electromagnetic wave on one or more two-dimensional sensing arrays comprising a plurality of sensing elements that are sensitive to the irradiated electromagnetic wave; determining, simultaneously, in a parallel manner, absolute values of sensed changes across different zones of the two-dimensional sensing arrays, each zone comprising one or more sensing elements; and summing the absolute values of different groups of different zones to obtain a representation of the perturbations.
