RT Journal Article T1 Mode analysis in optics through fractional transforms A1 Alieva Krasheninnikova, Tatiana A1 Bastiaans, Martin J. AB The relationship between the mode content and the fractional Fourier and fractional Hankel transforms of a function is established. It is shown that the Laguerre-Gauss spectrum of a rotationally symmetric wave front can be determined from the wave front's fractional Hankel transforms taken at the optical axis.
