Fiber optic pressure sensor light intensity unit

Home / Fiber optic pressure sensor light intensity unit

Intensity-based fiber optic pressure sensors rely on changes in the intensity of the light transmitted through the fiber. 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. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time.
