The authors have developed a Fabry-Pérot laser interferometer system for displacement measurement, which is compact and can be used as a stand-alone local strain measuring system. Interferometry operates on the principle of interference of a coherent light source and therefore provides an absolute standard of measurement. The purpose of this development is to investigate the extent of the linear-elastic range of geomaterials in triaxial stress space, and to obtain values of stiffness which can subsequently be compared with those obtained in other ways, both in the laboratory (using resonant column or bender elements) and in the field (using field geophysical techniques). The interferometer is also suitable as a high-accuracy instrument for calibration of other linear displacement transducers. This paper describes the instrument configuration and evaluates the performance of a commercial LVDT calibrated against the interferometer.
