AbstractWe report a miniaturized wavelength interrogator for the static and dynamic strain fiber Bragg grating sensors. The developed interrogator is based on a monolithically integrated echelle diffractive grating and works in two independent modes, one for the static strain measurement and the other for dynamic strain measurement. The proposed interrogator is evaluated by measureing a static strain of 400 με and a dynamic strain of 200 Hz with a peak-to-peak amplitude of 200 με. Initial results are excellent and show that these two interrogation modes can be potentially performed simultaneously. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).
