dcterms:description
Off-axis holographic diffractive optics creates beams with an elliptic cross section. Focusing properties of that beams differ from beams having a circular aperture. Axial intensity distributions of converging spherical waves behind elliptic apertures are analyzed. Similarly to behaviour of circular cross section beams, main maxima move from the geometric focus to the location of the aperture with decreasing the Fresnel number. However, their displacements and values are higher than for the circumscribed circular aperture. Minima of curves do not achieve zero values as expected. All results can not be given in closed form; only numerical results for specific parameters can be computed. Off-axis holographic diffractive optics creates beams with an elliptic cross section.
