Wide angle near-field diffraction and Wigner distribution

J. B. Almeida, V. Lakshminarayanan

Free-space propagation can be described as a shearing of the Wigner distribution function in the spatial coordinate; this shearing is linear in paraxial approximation but assumes a…

Wigner distribution transformations in high-order systems

J. B. Almeida, V. Lakshminarayanan

By combining the definition of the Wigner distribution function (WDF) and the matrix method of optical system modeling, we can evaluate the transformation of the former in centered…
