High SNR Φ-OTDR Based on Frequency and Wavelength Diversity With Differential Vector Aggregation Method
יצא לאור 2020-01-01קבל טקסט מלאPhase-demodulated phase-sensitive time domain reflectometer (Φ-OTDR) has attracted much attention because of its linear relationship between the phase variation and the amplitude of the vibration. However, it suffers from limited signal-to-noise ratio (SNR) and signal fading, due to the i...

Slow-Light Effect and Mode Selection of Double Fiber Ring With a Fiber Bragg Grating
יצא לאור 2018-01-01קבל טקסט מלאA novel slow-light reflector composed of a double-ring resonator with a uniform fiber Bragg grating (FBG) incorporated is proposed in this paper, which can be used as a mirror of narrow-linewidth fiber laser, based on its enlarged group delay, and as a high-sensitivity sensor. Its characteristics ar...
