Fractional Fourier transform in information optics

David Mendlovic, Zeev Zalevsky

Research output: Contribution to journalConference articlepeer-review


The fractional Fourier transform (FRT) operation is an important tool for various spatial filtering and signal processing applications. The FRT is a private case of the ABCD matrix. FRTs are interpreted based on propagation in graded index media and on Wigner distribution function. Both definitions are proven to be identical.
