Research Interest

Optics has traditionally been an important research area for our Group. Our field in optics could be shortly described as modelling of optical effects in virtual computational environments. The utilization of three basic components – numerical models of elastic dynamically interacting bodies, a physical model describing interference effects occurring whenever optical whole field fringe based experimental techniques are used to investigate these bodies, and the construction of digital graphical representations helps to mimic realistic optical processes taking place in those systems. And not only – such tools help to interpret complex optical phenomena and help to develop new measurement techniques. We managed to propose several new measurement techniques and improvements of existing measurement techniques – time average photoelasticity; time average stochastic moire; time average geometric super moire; the generalization of Abel transform for vibrating tubes; corrections of classical formulas describing time average projection moire and time average geometric moire. The range of investigated systems is quite wide: from MEMS up to fluids, membranes, or bodies with fractal surface geometry. Investigations of optical phenomena originated new numerical cryptographic methods and initiated the development of specialized numerical techniques.
