摘要: An improved optical implementation of the Radon-Wigner display for one-dimensional signals based on fractional Fourier transform is proposed. All of the fractional Fourier transform orders with the correct magnification can be achieved simultaneously by the suggested new setup with high precision, which consists of only two optical elements, a cemented linear varifocal lenses and a curvy image plane. This setup can offer practical applications for analyzing and processing of stationary or non-stationary signals.
