Abstract

The method of Fourier optics is applied to the problem of time-gated imaging through scattering media. To adapt the problem to this treatment, appropriate alterations are made: The continuous medium is replaced by a cascade of thin scatterers, and a spatial filtering process is substituted for the conventional gating processes. Closed-form solutions are derived.
