Abstract
An optical implementation of the fractional Fourier transform (FRT) with br oadband illumination is proposed by use of a single imaging element, namely , a blazed diffractive lens. The setup displays an achromatized version of the FRT of order P of any two-dimensional input function. This fractional o rder can be tuned continuously by shifting of the input along the optical a rris. Our compact and flexible configuration is tested with a chirplike inp ut signal, and the good experimental results obtained support the theory.
