Paper Abstract
We present an analysis of the reconstruction through any intermediate plane by using the cascaded Fresnel diffraction
integrals. The realization of the integral with the single fast-Fourier-transform (FFT) imposes inherently the constraints
on the pixel resolution and the field of view of the computation window in the intermediate plane. On the other hand,
according to the optical diffraction field of the band-limited object, the size of the diffraction field including most
energy exhibits a change with the intermediate plane in a different way. Since the field of view of the computation
window is usually smaller than the corresponding optical diffraction field, then the simply cascaded FFT-Fresnel
diffraction integral algorithms will lose the resolution and degrade the image quality. It is proposed to improve the
reconstruction by compensating the field to be close to the optical diffraction field and using the new field as the
computation window in the intermediate plane. The numerical simulation and the experimental data-based calculation
are performed and demonstrate our proposal.
