Preprocessing for Interference Fringe of Spherical Object Wave

Abstract:

A simple preprocessing method for interference fringe of holograms generated between spherical object wave fronts and plane wave reference is suggested. The formulae to calculate the diameters of the interference concentric circle and then to get the radius of spherical wave are deduced strictly and the flowchart for the algorithm is given clearly. By using the proposed method the characteristics of a spherical object wave can be achieved directly with only one recording frame and then a simulated one can be gained by numerical simulation. The corresponding experiments show that this technique is simple, effective and convenient for use.
