Abstract

We present an annularly distributed phase-only mask that generates an axial irradiance distribution identical to the point spread function of the Dowski-Cathey lens [Appl. Opt.34, 1859 (1995)]. This apodizer has an ambiguity function with a bow-tie effect, and consequently its axial modulation transfer function varies slowly with spherical aberration.
