Abstract :
We characterize the steady-state strain characteristics of an all-fiber distributed Bragg reflector (DBR) laser sensor interrogated using a wavelength-to-power mapping system. We also demonstrate that the system is capable measuring dynamic strain from four parallel DBR sensors without crosstalk.
