Abstract
A new fiber implementation of a grating interferometer for studying in- plane displacements of an object under load is presented. Applications of a fiber optic grating interferometers include laboratory and out of the laboratory tests of materials, construction elements and solving various mechanical problems, especially when a small sensor size is required. The system was tested for a specimen loaded in a four point bending configuration and phase methods for computer aided fringe analysis were implemented.
