An off-axis elliptical zone plate (EZP) together with refractive optics has been used for obtaining the 2-D nonsymmetric Fourier transform (NFT) of a given object with parallel beam illumination. The NFT thus obtained is exact, excepting a linear phase factor due to the carrier spatial frequency used in the EZP recording. Experimental results show the ability of this system for separating quasi-unidimensional spectra of slightly different orientation.
