Abstract

Experimental data on the angular dependence of the amplitude function of the edge diffraction wave originating behind a metallic knife edge that is illuminated nonenlarged laser beam are represented. It is shown that the scalar diffraction theory approximation (in particular, so-called `Rubinowicz's representation of the Kirhhoff's diffraction integral) is valid up to the diffraction angle approximately 20⁶. Outside this angular region (especially at the diffraction angle from 60 degree(s) to 90 degree(s)), considerable polarization dependence of diffraction are observed. The obtained experimental data are discussed using various vector theories of diffraction. On the base of these results, some consequences of the scalar Young-Rubinowicz model of diffraction in holography are derived. In particular, the impulse response of a Young hologram is constructed following to Fourier optics approach, and the nature of the double contouring effect at the reconstruction of such a hologram is elucidated.
