3D locations of the object directly from in-line holograms using the Gabor transform

In-line holography is a simple way for small object imaging. The Gabor transform is used for object characterization directly from in-line holograms. Three-dimensional locations of an object can be determined from the Gabor transform spectrum of its in-line hologram. The relationship between the Gabor angle and the location of the object is established, Computer simulations and experimental result have been presented to demonstrate the validity of this method for object charactering. The promising application of this method is particle field analysis.
