Fast FRFT-based method for estimating physical parameters from Newton ’ s rings

By analyzing Newton ’ s rings, often encountered in interferometry, using fractional Fourier transform (FRFT), we can estimate the physical parameters, such as the curvature radius of the spherical surface and the rings ’ center. However, parameter estimation from large images using FRFT ...
