Calibration and evaluation of optical systems for full-field strain measurement

By E.A. Patterson, E. Hack, P. Brailly, R.L. Burguete, Q. Saleem, T. Siebert, R.A. Tomlinson and M.P. Whelan


The design and testing of a reference material for the calibration of optical systems for strain measurement is described, together with the design and testing of a standardized test material that allows the evaluation and assessment of fitness for purpose of the most sophisticated optical system for strain measurement. A classification system for the steps in the measurement process is also proposed and allows the development of a unified approach to diagnostic testing of components or sub-systems in an optical system for strain measurement based on any optical technique. The results described arise from a European study known as SPOTS whose objectives were to begin to fill the gap caused by a lack of standards
