#### Abstract

The main goal of presented thesis is development of novel combined GI (Grating Interferometry) and DSPI (Digital Speckle Pattern Interferometry) technique for measurements and monitoring of displacement/strain in plane and non-plane objects. The goal was achieved via development of combined method concept and its application in measuring system, which allows full-field in-plane displacement measurements of technical objects. During the laboratory work three possible solutions of measuring system were developer (laboratory system, microscope head, independent interferometric sensor). All mentioned systems utilize modular design, which allows further modifications. In the thesis detailed analysis of opto-mechanical design and tolerances, of GI/DSPI interferometer, were performed. Most of optical elements used are easily available on market, except the air-cavity based waveguide interferometric (GI/DSPI) head, which is the ―heart‖ of the system. The optical properties of designed interferoemtric head were thoroughly analyzed (including polarization and diffraction properties). Additional outcome of work are analysis of manufacturing methods of GI/DSPI heads by means of microsystems technologies. The series of test of all system components were performed along with verification of implemented novel, combined method. The results of thesis can be used as directions for manufacturing of group of new sensors which will fulfill demands of people involved in experimental mechanics research.
