摘要：
In this invited talk, three advanced methods to improve both the spatial resolution and the measurement range are presented which paves the way for new horizons in high-end applications. The first one is to develop an optical source with ultra-highly-linear frequency sweeping rate, and use it for optical frequency domain reflectometry (OFDR). The second one is to use linear optical sampling (LOS) technique to measure ultra-short pulse used for optical time domain reflectometry (OTDR) and adopt dispersion compensation scheme. The third one is to use LOS technique for characterizing the ultra-wide linearly chirped signals for pulse compression.
