Specifications

the numerical simulation shows that more than 1000 FBGs can be multiplexed in OTDR-FBG
strain measurement system for a larger strain measurement range. Furthermore, the
corresponding driving circuits for nanosecond pulse and temperature control circuits are
designed for laser pulse modulation and frequency stabilization control. A OTDR-FBG strain
measurement system is developed by using 10 FBGs with the reflectivity of less than 5%, and the
system distance resolution of 43 cm is obtained, which verified the feasibility of the system. ©
