## Abstract (arXiv)

We demonstrate single-shot compressive three-dimensional (3D) (x, y, z) imaging based on interference coding. The depth dimension of the object is encoded into the interferometric spectra of the light field, resulting a (x, y, λ) datacube which is subsequently measured by a single-shot spectrometer. By implementing a compression ratio up to 400, we are able to reconstruct 1G voxels from a 2D measurement. Both an optimization based compressive sensing algorithm and a deep learning network are developed for 3D reconstruction from a single 2D coded measurement. Due to the fast acquisition speed, our approach is able to capture volumetric activities at native camera frame rates, enabling 4D (volumetric-temporal) visualization of dynamic scenes.
