Web30 Apr 2012 · The measurement apparatus uses the Pound-Drever technique, which employs an RF phase modulator and a Fabry-Perot cavity to produce a sensitive high-speed frequency discrimination signal. The authors show that this signal can also be used to measure the quantum noise contributions to the frequency spectrum of a laser oscillator. WebDue to the high sensitivity and quick response, the Pound-Drever-Hall (PDH) technique is one of the most successful interrogation methods in the high resolution fiber grating sensor systems. However, the traditional PDH technique can only interrogate one sensing element with limited measurement range, and can't fully exploit the capability of optical fiber … machitun definicion
