Abstract

Fourier lensless holograms of large size and large viewing angle are investigated. The investigated hologram is non paraxial and has large size in horizontal direction and small in the vertical one. This paper focuses on the problem of efficiency and quality of numerical reconstruction of such large holograms. Three wavefront propagation methods are analyzed for this task: (i) Fresnel propagation, (ii) classical Angular Spectrum and (iii) Angular Spectrum with optimized zero padding. All the numerical approaches are investigated theoretically and experimentally for its numerical efficiency and reconstruction errors. Experimental verification is provided.
