Wavelength Swept 모드 록킹된 광섬유 레이저를 이용한 광주파수 영역에서 반사계
Optical frequency domain reflectometry based on Wavelength swept mode locked fiber laser
초록
We demonstrate a novel OFDR system with compactness and short measurement time based on the use of a wavelength-swept mode-locked fiber laser. The optical source uses an intra-cavity tunable Fabry-Perot filter as a tuning element. The fiber laser sweeps 20 nm in less than 10 ms. Spatial resolution of 100 fm and total measurement range of several centimeters are demonstrate
