Abstract

In this talk, Abbie will present an overview of imaging through degraded environments such as turbid water and dense fog using range-gated digital holography. Digital holography provides the unique ability to separate out ballistic photons in a scattering and turbid environment through range-gating, coherence gating and polarization gating. The complex fields of the detected holograms and then post-processed using coherent averaging, incoherent averaging and singular value decomposition techniques to improve the SNR and reconstruct imagery in extremely challenging imaging conditions.
