Abstract
Holographic measurement techniques based on optical interferometry theory are widely applied in such areas as mechanics, electronics, computer industry, etc. One of limitation of practical method application is complicated interpretation of holographic interferograms because quantitive analysis is directly related with properties of the analyzed object and with structure of experiment itself. The optical measurement (holographic interferometry) data processing system is presented for identification of characteristics of dynamic of 3D components of mechatronic construction. The system uses optical view and mathematical model of experiment as input data producing the qualitative description of analyzed mechatronic system. Mathematical model of the experiment is built using the geometry of the measurement, elasticity theory and finite element method. The proposed method for identification of the properties of the analysed system has important advantages over other similar digital hologram interpretation schemes as the applied calculation principle is based on the natural eigenmodes of the analysed system. Such approach enables to decrease the volume of calculations without losing accuracy.
