Abstract

Holographic interferogram generation method is developed for the analysis of micro vibrations occurring in elastic structures with external thermal load. Digital geometrical scheme for the construction of holographic interferogram as well as finite element model of the system are developed to consider more general structure of analysed systems. Such a development of time average digital holography method enables more qualitative assessment of holographic images and processes taking place in dynamic structures exposed to more complicated environmental conditions.
