Limitations of diffraction measurements by means of axicons

Palchikova I.G., Smirnov S.V.

Abstract

Asymptotic and numerical evaluation of the Fresnel diffraction integral for intensity distribution in the axial focal segment of conical axicon was accomplished to find the H coordinate of maximum in cases of monochromatic or polychromatic illumination. The experimental and theoretical values of H coordinate were found to be in good agreement. It has been shown that the axicon focal segment can be used as a tape-line for the length measurement.
