I. What are Intrinsic Fiber Optic Sensors?
Intrinsic fiber optic sensors are a type of sensor that relies on optical fiber transmission and optical signal processing. They convert changes in the state of the object being measured into variations in optical signals, enabling real-time monitoring and measurement of the target. In this type of sensors, sensing takes place within the fiber itself. The sensors depend on the properties of the optical fiber to transform an environmental action into a modulation of the light beam traversing it. Here, the physical properties of the light signal may manifest as frequency, phase, polarization, or intensity.
II. Working Principles
The working principles of intrinsic fiber optic sensors primarily stem from physical phenomena such as interference, scattering, and diffraction. Through demodulation and analysis of optical signals, relevant information about the object being measured is extracted.
III. Features and Advantages
· High sensitivity and precision: Intrinsic fiber optic sensors can accurately measure minute physical quantities, offering high sensitivity and precision, making them suitable for various precision applications.
· Strong resistance to electromagnetic interference: Since fiber optic transmission uses optical signals instead of electrical signals, these sensors exhibit excellent electromagnetic interference resistance, ensuring stable operation in complex electromagnetic environments.
· Corrosion, high-temperature, and high-pressure resistance: Optical fiber materials possess excellent corrosion, high-temperature, and high-pressure resistance, allowing intrinsic fiber optic sensors to function stably in harsh environments for extended periods.
