Convolution, filtering, and multiplexing in fractional Fourier domains and their relation to chirp and wavelet transforms
TL;DR: Convolution, filtering, and multiplexing of signals in fractional domains are discussed, revealing that under certain conditions one can improve on the special cases of these operations in the conventional space and frequency domains.
Journal ArticleDOI
Optimal filtering in fractional Fourier domains
TL;DR: In this article, the authors consider filtering in fractional Fourier domains, which enables significant reduction of the error compared with ordinary Fourier domain filtering for certain types of degradation and noise, while requiring only O(N log N) implementation time.
Journal Article
Digital decoding of in-line holograms
Levent Onural,Peter D. Scott +1 more
TL;DR: The proposed filter is a truncated series expansion of the inverse of that operator that maps object opacity function to hologram intensity, which is shown to be equivalent to conventional (optical) reconstruction, with successive terms increasingly sup-pressing the twin image.
Journal ArticleDOI
State of the Art in Holographic Displays: A Survey
TL;DR: In electro-holographic displays, holographic polymer-dispersed, and acousto-optic devices are used as holographic displays as mentioned in this paper, which are based on physical duplication of light distribution.

TL;DR: In this paper, a truncated series expansion of the inverse operator that maps object opacity function to hologram intensity was proposed, which is shown to be equivalent to conventional (optical) reconstruction, with successive terms increasingly supressing the twin image.
