Abstract

A new version of a diffraction microscope developing the Young eriometer concept is presented. Recording of the near-field pattern is considered in the terms of the Young model of diffraction phenomena. According to the Young diffraction paradigm, a diffraction wave is divided in the direct (primary) wave and the secondary one retransmitted by the edge of a diffraction screen. Being readout with the primary wave, the recorded near-field pattern reconstitutes a contour image of the diffraction screen. A near-field concept is defined in the framework of the Young's approach. It is shown that the notion 'far field' is indefinable for an arbitrary convex opaque screen. That fact enables the construction of a microscope for a small particle contour imaging using a Young hologram as the diffraction objective. The Young holography method is compared with Michelson's experiment as well as B. Thompson's method of holographic microscopy using Fraunhofer holograms.
