Sampling Rate Chosen to Ensure Unitary and Additive Properties for the 2D Non-separable Linear Canonical Transform
Liang Zhao, Inbarasan Muniraj, John J. Healy, John T. Sheridan · 2015
The linear canonical transform can model a wide variety of paraxial optical systems. The continuous transform is additive & unitary, sampling rate chosen to ensure these two important group properties during discretization are summarized.
