Paper Abstract

An optical spatial filtering system, designed to operate with totally incoherent light sources is presented. When correlating with such polychromatic light sources, one major problem is the dependence of the correlation response scaling on wavelength. A theoretical system that exactly compensate for this problem is analyzed. A practical configuration for implementing such a system, satisfying the theoretical solution up to first order in wavelength, is proposed. This configuration includes a combination of diffractive and refractive lenses and a gray scale filter. The possibility of higher order approximations is considered.
