Paper Abstract

We have developed compressed ultrafast holography (CUH) to reconstruct the optical field of dynamic scenes in a single camera snapshot. In CUH, each row of the phase mask on the reference beam has a distinct carrier frequency. When the object interferes with the phase mask, each row will be shifted to a different location in the Fourier domain. Then, the interfered object and reference beam is swept across a camera during a single exposure to encode the temporal information. Since these shifts in Fourier domain will be overlapping, compressive sensing is applied to reconstruct the dynamic scenes.
