Optimum detection using the Wigner distribution function

Annual Meeting Optical Society of America, 1985
The use of the Wigner distribution function (WDF) as a signal processing technique has recently been recognized. One interesting application is signal detection and classification. The simplest (but nonoptimal) approach to signal detection is to use a filter in the time-frequency (ω-t) plane that is matched to the WDF of the signal; in fact, this has ...

Wigner distribution function applied to third-order aberrations

Applied Optics, 1996
The Wigner-distribution-function description of light beams is extended to aberrated optical systems. The simulations performed show that the different types of aberrations can be identified separately by the use of experimental devices that display projections of the Wigner distribution function of a two-dimensional beam.

The Wigner distribution function of self-Fourier functions

Journal of Modern Optics, 1996
Particular forms of the Wigner distribution function and its moments of arbitrary order are derived for a generalized definition of the self-Fourier functions. The general form of the optical system matrix for which an input self-Fourier function transforms to an output self-Fourier function is found.

Wigner distribution function for paraxial polychromatic optics

Optics Communications, 1996
Polychromatic paraxial wavefields and their color images on a screen are provided here with a Wigner distribution function of position, momentum and wavelength. The definition is based on the Heisenberg-Weyl group. In the monochromatic limit we return to the common Wigner function and phase-space formalism.
