Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademicpeer-review


The more attractive first-order optical systems such as a (fractional) Fourier transformer, a gyrator, and an image rotator [1] – used, among other applications, for optical information processing, including pattern recognition, encryption, and filtering; transversal mode conversion; and tomographic methods of coherence state estimation – correspond to different kinds of rotations in phase space. All such systems that produce phase-space rotations are described by an orthogonal ray transformation matrix.
