title = "The parameter estimation of interference fringes with quadratic phase based on FRFT/DCFT",
abstract = "Interferometry technology has a wide range of applications because of high accuracy and sensitivity, the core of which is the processing of interference fringe pattern. The interference fringes with quadratic phase are very common in interferometry measurement, which means that any sophisticated interference fringes can be decomposed or approximatively decomposed by them. Newton{\textquoteright}s rings are typical interference fringes with quadratic phase, the physical parameters such as curvature radius and position of ring{\textquoteright}s center are included in the pattern. The parameter estimation algorithm of Newton{\textquoteright}s rings based on FRFT/DCFT needs only one pattern to realize the estimation through the method of signal processing with advantages of easy operation, high accuracy, high speed and strong anti-noise performance, for reason that the Newton{\textquoteright}s ring is actually a two-dimension Chirp signal.",
