摘要
The automated system for microelement testing, which consists of Twyman-Green interferometer and waveguide grating interferometer integrated with optical microscope is presented. The microscope is additionally equipped with mechanisms to fix, microposition and load a specimen under study. Full-field analysis of out-of-plane and in-plane displacements of microelements is performed at this study. The applicability of the system is proven by performing tests of silicon membrane and silicon beam.
