Abstract
The effect of unwanted interferometric signals on the wavelength detection accuracy in a fiber Bragg grating sensor using a tunable laser and a first derivative interrogation technique are investigated. The wavelength detection error can be reduced significantly by proper modulating the laser wavelength.
