Laser Frequency Noise Cancelation in a Phase-Shifted Fiber Bragg Grating Ultrasonic Sensor System Using a Reference Grating Channel
In an ultrasonic sensor system based on π phase-shifted fiber Bragg gratings (πFBGsÞ, a cost-effective way for sensor demodulation is to set the laser wavelength at the center of the steep spectral slope of the πFBG refection spectrum. Frequency noise of t...
