Fiber Optic Sensor Products

Fiber optic sensors are advanced devices that use optical fibers to detect and measure physical parameters such as strain, temperature, pressure, and displacement across diverse industrial and research applications.

Overview of Fiber Optic Sensor Technology

Fiber optic sensors operate by transmitting light through a glass or plastic optical fiber, which interacts with the environment to detect changes in physical properties. The light signal is then converted into an electrical signal for analysis. These sensors are highly suitable for tight spaces, harsh environments, and applications requiring high precision due to their immunity to electromagnetic interference and small form factor .

Types of Fiber Optic Sensors

1. Point Sensors: Measure a single location, commonly used for temperature, pressure, or displacement monitoring.
2. Distributed Fiber Optic Sensors (DFOS): Provide continuous measurements along the entire fiber length, enabling monitoring of large structures for strain, temperature, or deflection .
3. Fiber Bragg Grating (FBG) Sensors: Utilize periodic variations in the fiber to measure strain and temperature with high precision and fast response .
4. Specialized Sensors: Include accelerometers, tilt meters, and terahertz sensors for aerospace, automotive, and industrial applications .
