Paper Abstract

We report a new achromatic Fourier processor constituted basically by a quasi wavelength- independent imaging forming system whose first half performs an achromatic Fourier transform of a color input object. Consequently, this optical architecture, formed by a small number of diffractive and refractive lenses, provides an intermediate achromatic real Fraunhofer plane and a final color image with a high signal-to-noise ratio. In this way, our optical processor can perform simultaneously the same spatial filtering operation for all the spectral components of the broadband illumination.
