Abstract

A temporally incoherent optical processor that combines diffractive and refractive components is proposed for performing two different operations simultaneously an achromatic image along an axis and an achromatic one-dimensional Fourier transformation along the orthogonal axis. These properties are properly employed to achieve the achromatic white-light display of the Wigner-distribution function associated with a one-dimensional real signal, with high redundancy and variable scale.
