Abstract

We introduce and experimentally demonstrate a new method of computing Fresnel holograms of a real-existing, three-dimensional (3-D) scene hidden behind a thin turbulent medium, and illuminated by incoherent white light. From each perspective point of view, we acquire multiple noisy speckled images through the medium vibrated mechanically. These images are fused together to yield a smoothed perspective projection of the hidden 3-D scene. All smoothed projections are processed to yield a Fresnel hologram of the hidden scene. The 3-D image reconstructed from the hologram is further improved by digital blind deconvolution of each of the 3-D image slices with its own estimated impulse response.
