About the Wigner distribution of a graded index medium and the fractional fourier transform operation
(SPIE, 1993-08)Upon propagation through quadratic graded index media, the Wigner distribution of the wavefunction of light rotates uniformly. As a consequence, a definition of fractional Fourier transforms based on rotating the functions ... -
Fourier transforms of fractional order and their optical interpretation
(Elsevier, 1993)Fourier transforms of fractional order a are defined in a manner such that the common Fourier transform is a special case with order a=1. An optical interpretation is provided in terms of quadratic graded index media and ...
