A simple optical sensor based on singlemode-multimode-singlemode (SMS) optical fiber structure is proposed and demonstrated for the measurement of steel beam compression strain. The SMS sensor probe is fabricated by splicing both ends of a short multimode fiber with two pieces of standard single-mod...
