Abstract
A phase-only filter for approximating a given optical transfer function for monochromatic incoherent light. The filter is designed by solving an integral equation for a phase function, and imposing, on a transparent plate, an optical path length for the incoherent radiation equal, in radians, to the phase function modulo 2.pi. plus an overall constant.
