Notes:
A high-strain optical fiber sensor system has been developed to provide a cost-effectivesolution for measurement of very large strain. The measurement of large strain in the order of a fewtens of % strain (up to 40 % strain) in geotextile materials has been achieved using an extrinsicplastic optical fiber sensor (POF). Based on this design, the sensor is not limited to operating withinthe elastic region of the plastic fiber proposed by other workers in the field. The present designallows for compression strains to be measured even after exceeding strain levels of 5% (typicalplastic strain values of POFs based on fiber stretching.) The POF were initially calibrated using alinear variable displacement transducer and the results based on tensile tests of a series of geotextilefabrics have shown to compare well with other reference measurements
