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.
