Interferometric sensors: Based on the Mach-Zehnder or Fabry-Pérot interference principles, pressure-induced optical path length differences alter interference fringes, enabling pressure estimation. Fiber-optic sensing (FOS) technology has emerged as a cutting-edge research focus in the sensor field due to its miniaturized structure, high sensitivity, and remarkable electromagnetic interference immunity. Compared with conventional sensing technologies, FOS demonstrates superior capabilities in. Fiber-optic sensors have transformed how we monitor the integrity of skyscrapers, the safety of aircraft, and even human vital signs. These intricate bands of light and dark, born when light waves.
