Abstract
An automated Young’s fringe processor for point filtering of speckle photographs is described. It automatically measures the magnitude and direction of displacements from fringe densities of less than twenty with good accuracies. Microcomputer-based, requiring <64K of memory, the system provides full automation by employing computer-controlled scanning.Keywords
