Dual Wavelength Differential Detection of Fiber Bragg Grating Sensors with a Pulsed DFB Laser
We show how dual wavelength differential detection can be used to measure fiber Bragg grating sensors using nanosecond pulses from a single DFB laser diode, by taking advantage of its dynamic chirp. This can be performed in two ways: by measuring the reflected power from two separate pulses driven b...
