Concise fractional Fourier transform based on a non-uniform order searching method for estimating physical parameters from Newton’s rings

Newton’s ring pattern is very common in interferometry. By analyzing it, the physical parameters can be estimated, such as the curvature radius and the rings’ center. However, parameter estimation from large images using fractional Fourier transform (FRFT) consumes considerable time. A concise FRFT...
