摘要：
Instrumentation and data postprocessing problems connected with local measurements of high gradient in-plane displacement/strain fields by automated grating interferometer are considered. A new version of waveguide grating microinterferometer is proposed. Various paths of postprocessing are investigated and data reduction and interpolation technique with adaptive size of elementary sampling area is recommended for strain and local material constant determination. The usefulness of the technique is shown on the base of ceramic-to-metal joint investigation.
