Paper Abstract

An Algorithm to compute the spacing of parallel fringes obtained from Digital Speckle Pattern. Interferometers (DSPI), based on. discrete autocorrelation calculations, is analyzed and experimentally verified_ It is found to provide sub-pixel resolution and is comparable with FFT analysis_ Experimental results confirm the algorithm performance_
