Paper Abstract

The Gabor expansion of an arbitrary optical signal in terms of Gaussian signals that form an NxM truncated von Neumann lattice in the time-frequency plane is studied. The accuracy of the expansion for various values of (NxM) and various widths of the Gaussians is examined. The accuracy of the method is also demonstrated by comparing and contrasting the Wigner function for both the original and reconstructed signals. Practical implementation of the method through ''Gabor analyzers" that directly measure the Gabor coefficients of optical signals is also discussed.
