A Comparative Analysis of Associative Properties of Fourier versus Walsh Digital Holograms

Abstract: A digital implementation of the Fourier holography scheme with identical reference and signal beams is considered. Investigations of the properties of this scheme were reported on in a number of papers. At the same time a concept of virtual optics is widely used in data encryption and data processing, whereas digital implementation of the Fourier holography scheme may be provided using not only discrete Fourier transform. Another discrete digital transform may be used as soon as it has several properties simil… Show more

“…In quantum mechanics and quantum computer science, an important role is played by unitary operators in form of Hadamard matrices with complete orthogonal systems of Walsh functions in them. Hadamard operators are also widely used for spectral representations of signal vectors in the technique of noise-immune communication [Seberry, Wysocki, Wysocki, 2005], the sequency analysis of Harmuth [Harmuth, 1977[Harmuth, , 1989, the digital logical holography [Derzhypolskyy, Melenevskyy, Gnatovskyy, 2007;Morita, Sakurai, 1973;Soroko, 1974] and algorithms of quantum informatics [Nielsen, Chuang, 2010]. But the Hadamard matrices with their complete systems of orthogonal functions are not the only unitary matrices with complete systems of orthogonal functions in them.…”

“…This algebra-logical Walsh-holography under the title «logical holography» was also considered later in [Derzhypolskyy, Melenevskyy, Gnatovskyy, 2007;Golubov, Efimov, Skvortsov, 1987]. All these and other works about logical Walsh-holography considered possibilities of its applications in engineering technologies of digital signals processing without any supposition of its application in biology, in particular, in genetics.…”
