Leading Fiber Optic Sensing Technologies

Fiber Bragg Grating (FBG) Sensors FBG sensors are widely adopted due to their high precision in measuring strain, temperature, and pressure. They are particularly effective in structural health monitoring, energy infrastructure, and aerospace applications.

FB

G sensors offer immunity to electromagnetic interference, chemical passivity, and a wide operating temperature range, making them suitable for harsh environments. Distributed Fiber Optic Sensors (DFOS) DFOS technologies enable continuous, real-time monitoring over long distances, ideal for pipelines, power grids, and perimeter security. They detect micro-strains and temperature variations along the entire fiber, providing high spatial resolution and early warning for structural or environmental changes.

Intensity-

Modulated Fiber Optic Sensors These sensors measure changes in light intensity caused by environmental factors. They are simpler and cost-effective for applications where high precision is not critical, such as basic industrial monitoring.

Phase-

Modulated Fiber Optic Sensors Phase-modulated sensors detect changes in the phase of light, offering high sensitivity for vibration and acoustic monitoring. They are used in specialized industrial and defense applications.
