A novel optical implementation of the Radon-Wigner display (RWD) was propos
ed based on the fractional Fourier transform. By using a point-like white-l
ight source, the RWD of a two-dimensional object can be easily achieved. Th
e transform angle of the RWD is continuously varied because the wavelength
component in the white-light source is a continuous distribution. (C) 1999
