What is the major of fiber optic sensor

Fiber optic sensors primarily belong to the fields of optical engineering, photonics, and electrical engineering.Fiber optic sensors are devices that use optical fibers to detect physical quantities such as strain, temperature, pressure, vibration, or electrical current by modulating light properties like intensity, phase, polarization, or wavelength . Because of their reliance on light propagation, optical principles, and signal processing, they are studied in optical engineering and photonics, which focus on the design and application of optical systems and devices . Electrical engineering is also a relevant major because fiber optic sensors often interface with electronic systems for signal detection, processing, and data acquisition . Subfields such as instrumentation and control engineering or electrical and electronics engineering cover the integration of fiber optic sensors into industrial, aerospace, and medical applications . Applied physics and materials science can also be involved, particularly when developing new fiber materials, improving sensor sensitivity, or studying light-matter interactions within the fiber . Applications across disciplines include:Structural health monitoring and civil engineering for bridges and buildings Power systems and current measurement in electrical engineering Aerospace and medical devices for precise, non-contact sensing In summary, students interested in fiber optic sensors typically pursue majors in optical engineering, photonics, electrical engineering, applied physics, or related interdisciplinary programs that combine optics, electronics, and materials science.
