Light diffraction at imperfect slit

The paper present a theoretical analysis of a Fraunhofer diffraction by an imperfect slit. Theoretical diffraction formulas are applied to the specific example and an effect of a ripped slit's shape is shown....

Frauenhofer diffraction from a ring aperture with a spiral phase transmission function: numerical and analytical studies.

Fraunhofer diffraction patterns from a spiral phase element with an annular aperture are investigated, on normal incidence of a plane monochromatic wave, depending on a spiral distribution of the phase of a wave at the output from t...

Diffraction efficiency of surface-relief gratings with various profiles.

Diffraction efficiency of surface-relief gratings with various shallow profiles is discussed. A general relation for the diffraction efficiency is derived under the assumption of Fraunhofer diffraction. The general...

Off-axis Fresnel diffraction approximation

Diffraction is analyzed for oblique propagation of light beam under a large angle. Fresnel diffraction approximation is valid provided the beam is deflected into the direction of oblique propagation, the structure of the diffrac...
