Steel Beam Compressive Strain Sensor Using Single-Mode-Multimode-Single-Mode Fiber Structure

IEEE Photonics Journal, 2016
A steel beam compressive strain sensor using single-mode-multimode-single-mode (SMS) fiber structure is demonstrated. Parallel measurements are made using an electrical resistance (ER) strain gauge along with the SMS to sense the compressive strain on ...
