Recording and Numerical Reconstruction of Digital Fresnel Holograms

Resumo

The scheme of digital Fresnel holograms recording with off-axis objective beam is considered, estimations of limiting parameters of registered objects are acquired. On the basis of the results experimental setup is created, digital Fresnel holograms in both modes of objectsillumination on transmission and on reflection are recorded. The obtained digital holograms are numerically reconstructed. Calculated and experimental values of the parameters are compared.
