Paper Abstract

The effect of truncating a light beam is expressed as a convolution of the Wigner distribution function of the light beam and the Wigner distribution function of the truncating aperture. The Wigner distribution function of a circular truncating aperture is derived and an approximate expression is presented. The approximation not only has the properties that it is exact in the spatial origin and in the spatial- frequency origin, but also that the integral over all spatial frequencies takes the exact value.
