Paper Abstract

Our goal in this paper is to make a comparative study about 4 f filters. The filters are in the same configuration and we study three different situations: - ideal case - aperture with one aberration - each lens with one aberration Aberrations are characterized by orthogonal Zernike polynomials; aperture and lenses have their proper transfer functions. We have an input signal and the purpose of this paper is to see how the properties of the input signal changes at the output in the three situations analyzed and to make a comparison between them.
