WAVE-FIELD DETERMINATION USING TOMOGRAPHY OF THE AMBIGUITY FUNCTION

Ambiguity function (AF) theory is proposed to reconstruct a complex wa ve field using tomography by measurements of intensity in a refractive optical system. By performing one-dimensional (1D) inverse Fourier tr ansforms of intensities with some adjustment in various longitudinal o ptical system parameters, the corresponding AF values along the lines at different angles in the AF phase: space are obtained; therefore, th e mutual intensity function is reconstructed by performing a 1D Fourie r transform of the reconstructed AF values. The reconstruction process in some cases is considered to be simpler than the equivalent theory using Wigner distribution function.
