Fiber Bragg Grating (FBG) based optical fiber sensors have been used in various applications such as oil & gas, renewable energy, aerospace, marine, civil & infrastructure, rail, nuclear and medical applications.

Currently, Flexilicate provides installation of FBG sensor for civil and infrastructure mainly for monitoring strain, temperature, pressure, and displacement. Two monitoring services can be offered, first is a real-time with continues detection and frequent sampling up to several times per day, which is more suitable for critical applications. The implementation cost of such system is relatively high as it required the full set of monitoring systems including the sensors, interrogator, and optical link.
