Direct pointwise analysis of double exposure specklegrams with digital image processing
A pointwise analysis method, which is used for obtaining Young's fringe patterns and measuring the magnitudes and directions of displacements by directly processing double exposure specklegrams with digital image technique, has been presented. In this procesure. If a proper speckle recording arrangement and a suitable magnifying power of the microscopic objective are selected, a high measuring sensitivity and accuracy can be obtained.
