Fiber sensing involves using optical effects in fiber Bragg gratings to measure the physical units of strain, vibration, and temperature precisely, in a galvanically isolated manner, and over long distances using interrogators. OCT (Optical coherence tomography) enables high-resolution surface measurements to be made, such as ones for precision engineering, with light of a low coherence length and an interferometer.
Here is a quick overview of the OCT (Optical Coherence Tomograhphy) testers from OCTPRO.
