Abstract
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.
