Euclidean systems include poly- and monochromatic wide-angle optics, acoustics, and also infinite discrete data sets. We use a recently defined Wigner operator and (quasiprobability) distribution function to set up and study the phase-space evolution of these models, subject to differential and difference equations, respectively. Infinite data sets and two- dimensional monochromatic (Helmholtz) fields are thus shown by their Wigner function on a cylinder of (2 ) direction and location; the…

Position and momentum bases for the monochromatic Maxwell fish-eye and the sphere
In geometric optics the Maxwell fish-eye is a medium where light rays follow circles, while in scalar wave optics this medium can only ‘trap’ fields of certain discrete frequencies. In the
Wigner functions for Helmholtz wave fields
We investigate a general form of the Wigner function for wave fields that satisfy the Helmholtz equation in two-dimensional free space. The momentum moment of this Wigner function is shown to
Finite Hamiltonian systems on phase space
We construct and analyze a Hamiltonian system whose position coordinate takes values on the finite subset of contiguous integers Zj := {−j,−j+1, . . . , j}, with the purpose of applying the resulting
Linear transformations and aberrations in continuous and finite systems
In geometric optics there is a natural distinction between the paraxial and aberration regimes, which contain respectively the linear and nonlinear canonical transformations of position and momentum
Finite optical Hamiltonian systems
In this essay we finitely quantize the Hamiltonian system of geometric optics to a finite system that is also Hamiltonian, but where signals are described by complex N-vectors, which are subject to
Wigner function for SU(1, 1)
TLDR
This work derives in a consistent way a Wigner distribution for SU(1,1), which appears as the expectation value of the displaced parity operator, which suggests a direct way to experimentally sample it.

TLDR
The Kravchuk coherent states provided by the finite oscillator model are used to evince the nonlinear transformations that elliptic-profile waveguides produce on phase space by means of the SO(3) Wigner function.

Euclidean optics are models of the manifold of rays and wavefronts in terms of coset spaces of the Euclidean group. One realization of this construction is the geometric model of Hamilton's optical
