Stochastic Optical Sensing

Abstract

The fluctuations of measured signals are not always artifacts. A variety of active sensing circumstances where the excitation fields interact with random potentials result in measured signals that fluctuate. As inverse problems are notoriously ill posed, only stochastic information is available in these conditions. Here, we demonstrate a stochastic sensing technique where the statistically non-stationary properties of the excitation fields are purposely manipulated such that the fluctuations of the scattered intensity are enhanced and further exploited to recover information about the interaction potentials. The numerical and experimental results establish the efficacy of this new sensing approach and validate its robustness against various sources of perturbations. A range of remote sensing and biomedical applications that rely on recovering the properties of random scattering potentials and are usually limited by noise could benefit from the sturdy performance of this sensing procedure.
