提出了一种基于可调谐光纤激光器的新型光频域反射计,该激光器具有很窄的线宽(约10 kHz)。该仪器以-110 dB的灵敏度和80 dB的动态范围进行反射率测量。窄线宽允许长距离测量,在150米,空间分辨率为16厘米。在近距离,约5米,分辨率增加到亚厘米。
The present a new optical frequency domain reflectometer based on a tunable fiber laser with a very narrow linewidth (about 10 kHz). This instrument performs reflectivity measurements with -110 dB sensitivity and 80 dB dynamic range. The narrow linewidth allows long-range measurements, at 150 m, with a spatial resolution of 16 cm. At short range, about 5 m, the resolution increases to subcentimeter.
