✦ Synopsis

The effect of lens with spherical aberration on the fractional Fourier transformation systems is introduced and analysed in this paper. Consider the fundamental mode Gaussian beam as an input function, the intensity distributions of the output field through the fractional Fourier transformation system with spherically aberrated lens are obtained by numerical calculation. The results show that different kinds or values of spherical aberration coefficient contribute to the output intensity distribution differently even for the same fractional order. It is also shown that LohmannÕs two types of optical setups with spherically aberrated lens for implementing the fractional Fourier transform are no longer equivalent.
