Abstract
A coherent processor to display the phase-space functions for 1-D signals is proposed. An elliptical zone plate is used as a single optical element. It is shown that, for a given 2-D input, the output plane shows the 1-D Fourier transform in one direction and the image in the other one. This lensless coherent processor can be used to display the Ambiguity Function, the Wigner Distribution Function and the Local Spectrum for some 1-D functions. Experimental results are presented.
