Imaging through scattering media with depth resolution by use of low-coherence gating in spatiotemporal digital holography.
We demonstrate optical gating through scattering media based on low-coherence spatiotemporal digital holography. The method combines the advantages of low-coherence gating, both temporal and spatial, with the advantages of methods using heterodyning and phase-sensitive detection. Spatiotemporal data are captured on a CCD detector in a single exposure, without mechanical scans, and processed digitally. Examples of reconstructions and sectioning of objects hidden behind a ground-glass diffuser are shown.
