Abstract

A number of optical techniques for measuring the dynamic motions of fluids and solids are based on quasielastic light scattering and detection by light beating (dynamic interferometry). Most of the methods are used for scientific investigations. The set-ups are generally bulky and delicate to operate. A considerable reduction in size can be obtained by applying diffractive (or holographic) elements.1,2,3
