Abstract

The effects of the limited extinction ratio of the optical pulse modulation on the detection sensitivity of the sensors and a first derivative interrogation technique were discussed. A theoretical analysis on crosstalks caused by incoherent and coherent effects due to limited extinction ratio of the optical pulse modulator was also discussed. The results showed that the wavelength detection accuracy limits the coherent mixing between the signal wave from one channel and the leakage waves from another channel.
