【摘要】A laser sensing system based on beat frequency demodulation is proposed. The sensor uses a single-longitudinal-mode distributed Bragg reflector (DBR) fiber laser as a sensing element. This laser sensor has great multiplexing capability due to its wide free spectral range. Wavelength-division-multiplex (WDM) and frequency-division-multiplex (FDM) techniques are studied. The sensing system has high sensitivity and multiplexing channels. 【总页数】3页(396-398) 【关键词】
