Abstract:

In this paper, we present the results of our investigation regarding the effect of a discretization period of an object on the depth of field of the reconstructed image. It was established that the use of the object-discretization period in the synthesis of the hologram, which is the maximum permissible period based on the spatial-frequency analysis of the discrete hologram, leads to an inverse dependence of the depth of field on the size of the object’s structural elements, in comparison to the traditional dependence for optical systems. Recommendations are made for choosing an object-discretization period that provides the traditional dependence of the depth of field on the size of the object’s structural elements for optical systems.
