Abstract

This paper presents a novel FPGA-based hardware architecture for realtime diffraction computation of digital holography. The hardware circuit is based on Fresnel transform in basic form for diffraction computation. A novel pipeline is adopted in the circuit so that all the components are operated concurrently. The computation time of the circuit is comparable to a single fast Fourier transform (FFT). Experimental results reveal that the proposed architecture has the advantages of high throughput, high accuracy and low power consumption for the 3D reconstruction of holograms.
