Abstract

Possibilities of obtaining quantitative information about the deformation influence on the SFMI with a small number of excited modes by using a correlation method are investigated. It was shown that usage of diffusive scatterer allows us to transform the radiation of SFMI to a speckle field which can easily be processed. The value of the measurement error of SFMI elongation is ±10 &mgr;m. The working range of the SFMI deformation measurements is 0 - 160 &mgr;m.
