Abstract:
As for the issue of the rapid wavelength interrogation of optical fiber wavelength-encoded sensor, a demodulation method combining spectrum-to-time domain information mapping and photonics time stretch technology is proposed. Using group velocity dispersion effect of dispersive elements, the spectrum of optical pulse will be mapped to a temporal waveform whose intensity mimics the spectrum. The temporal waveform is further stretched in timescale so that it is slow enough to be captured by electronic analog-to-digital converter. The performance of the proposed demodulation method is experimentally demonstrated to demodulate a wavelength-encoded sensor. (C) 2018 Society of Photo-Optical Instrumentation Engineers (SPIE)
