Why is the Linear Canonical Transform so little known?
AIP Conference Proceedings
The linear canonical transform (LCT), is the name of a parameterized continuum of transforms which include, as particular cases, the most widely used linear transforms and operators in engineering and physics such as the Fourier transform, fractional Fourier transform (FRFT), Fresnel transform (FRST), time scaling, chirping, and others. Therefore the LCT provides a unified framework for studying the behavior of many practical transforms and system responses in optics and engineering in general.doi:10.1063/1.2361224 fatcat:mxgaudkjbrcqnl3kyo3yj2bneu
