A Holographic Optical Element for Non-symmetric Fourier Transform Systems

Abstract
Up to now, the non-symmetric Fourier transform (NFT) of an object has been made using conventional refractive optics such as cylindrical and/or spherical lenses. In this paper, we propose the use of a holographic optical element in conjunction with refractive lenses to improve the design flexibility of NFT systems working with parallel beam illumination. Experimental results are presented.
