As a consequence, a definition of fractional Fourier transforms based on rotating the functions Wigner distribution, and another based on propagation through graded index media, are equivalent.EnglishFourier transformsFractional Fourier transformLight wavefunction rotationQuadratic graded index mediaWigner distribution functionOpticsConference Paper10.1117/12.2308583
