The measurement of strain is critical in many engineering design, test, and health monitoring procedures. Despite the promise of non-contacting and remote strain measurement, optical techniques have not been widely adopted by industry; the preference being the use of electrical resistance strain gauges. This is due to the perceived and real complexities of many optical techniques. [Continues.]
