A geometric interpretation, based on use of the Wigner distribution function, is presented to describe this application of the optical fractional Fourier transform when little prior information is known about the motion.||Funding Details:||Other funder||Type of material:||Journal Article||Publisher:||Optical Society of America||Copyright (published version):||2003 Optical Society of America||Subject LCSH:||Wigner distribution
