Paper Template for Digital Speckle Interferometry Method for Research of Dynamic Processes
The new digital speckle interferometry method for research of processes in mechanics of fracture, fatigue and strength of solid materials and structures in real time is considered. The new method is based on simultaneous registration of information by the standard digital speckle interferometry method and registration of distribution of intensity in the single speckle. Such decision allows to investigate fracture processes in real time; to increase sensitivity and accuracy of measurements; to expand a range of measured displacements. Besides, an offered method of the analysis of distribution of intensity in the single speckle allows will get rid of own noise inherent of interferometric methods of coherent optics. In work theoretical and experimental results on realization of an offered method are presented. The optoelectronic scheme the digital speckle interferometer for registration at the same time speckle interferograms and intensity distribution in the single speckle is presented. The algorithm of processing of speckle interferograms on an offered method is presented.
