Optical Sectioning For Optical Scanning Holography Using Phase-Space Filtering with Wigner Distribution Functions

We propose a novel optical sectioning method for optical scanning holography, which is performed in phase space by using Wigner distribution functions together with the fractional Fourier transform. The principle of phase-space optical sectioning for one-dimensional signals, such as slit objects, and two-dimensional signals, such as rectangular objects, is first discussed. Computer simulation results are then presented to substantiate the proposed idea. (c) 2008 Optical Society of America.
