Members of the group deal with the problems of wave optics and development of applications of measurement methods based on the principles of wave and statistical optics. Theoretical results are focused on the advances in complex theory of statistical properties of optical speckle fields including novel numerical model (Sci. World J. 2014, 704368) simulating generation and propagation of speckle fields for various variants of deformation tensor characterizing the surface of the object (rigid body translation, 3D rotation or tranlsation, elastic deformation). Suggested approach has been tested also experimentally in good agreement including determination of limits of applicability, sensitivity and precision.
The methods of wave optics have been also used to noninvasive observation of plants exposed to wound (Plant Meth. 2018, 14 , 38).
Next, problems of various applications of electronic speckle pattern interferometry (ESPI) are studied, e.g., effective evaluation of highly noisy interferograms (Meas. Sci. Rev. 2014, 14, 177). As another task, the methods based on white-light interferometry are investigated and applied as 3D sensors with large information potential.
