Abstract

Compressive Fresnel holography is an application of compressive sensing to Fresnel digital holography that can reconstruct a complex field from a sub-sampled Fresnel diffraction pattern. This reconstruction requires relatively long computation time. In this study, we accelerated the reconstruction in compressive Fresnel holography using a graphics processing unit (GPU). Our GPU-accelerated reconstruction was up to 30 times faster than CPU-based reconstruction.
