The paper deals with design and implementation of an optical extensometer based on grating (moire) interferometry, for large engineering construction monitoring. The paper presents the principles of the grating interferometry and the construction of miniaturized and portable version of grating interferometer and its implementation for out-door measurement directly at civil engineering structures. The paper presents also a concept of the low-cost full-field optical extensometer.
