Paper Abstract

A recently published system for determining the spacing and direction of speckle photography fringes is tested for accuracy and computer run time through a computer simulation that includes the degradation of data by noise. Compared with a previously published processing method, the algorithm used in the new system determines fringe direction with higher accuracy and reduced computational effort. From the evaluation of fringe spacing, displacement components are also determined as a function of fringe density, visibility, and image resolution. Errors in displacement components are compared with those obtained using other algorithms.
