Low-cost effective characterization methodology was developed that allows indirect evaluation of mechanical,
geometrical and optical parameters of periodical microstructures in the cases when traditional measurement techniques
are not suitable. Proposed methods are applicable for optimization and control of technological processes.
Laser diffractometer is used in the experimental works for measurement of optical parameters of periodical
microstructure and estimation of geometrical parameters with an error of less than 5% by comparing theoretical and
experimental values of diffraction efficiencies of periodical microstructures. This method is suitable for geometry control
of periodical microstructures during all technological process.
Also an efficient method was developed that is capable to estimate with an error of 5% the depth of periodical microstructures, which have characteristic depths that are larger than the wavelength of coherent light used in the experiment.
Quality of periodical microstructures is sensitive to thermal conditions during replication process. Therefore an experimental setup based on Michelson interferometer was developed for the investigation of induced thermal deformation. The radius and stress kinetics could be analyzed for different thickness of coated polymer.
These are the problems that are considered in this paper.
The purpose of the paper is the development of techniques for hybrid experimental - numerical photoelasticity analysis. The general scheme of such analysis is presented. Generation of digital images mimicking the effect of photoelasticity naturally incorporates into the hybrid iterative procedure enabling effective interpretation of experimental results of Investigation Smart structures and provides insight into the physical processes taking place in the analysed objects. Visualization techniques of the results from finite element analysis procedures are important due to several reasons. First is the meaningful and accurate representation of processes taking place in the analyzed smart structures. Second, and perhaps even more important, is building the ground for hybrid numerical - experimental techniques. A typical example of FEM application in developing a hybrid technique is presented in paper.
