Abstract
Three-dimensional (3D) targets can be simultaneously located and recognized in 3D space using two-dimensional scanning holographic correlation and Wigner analysis of the correlation data. The accuracy of target location in the presence of additive intensity noise is estimated from computer simulations. It is shown that with a sufficiently high signal-to-noise ratio, the target can be located in the transverse plane as well as axially with an accuracy that can exceed considerably the resolution limit fixed by the numerical aperture of the optics.
