| Research Abstract |
For providing efficient solutions to the difficult problems in diagnoses of optical fiber subscriber access networks, this project proposed and established advanced optical reflectometry techniques by making use of optical frequency comb sources, realizing high performance optical reflectometry with fine spatial resolution, long measurement range and high accuracy, high sensitivity and large dynamic range, high stability and high speed, in parallel. Furthermore, the newly proposed and demonstrated techniques also contribute to the development of distributed and multiplexed fiber optic sensors. Related to the achievements of this project, 18 peer-reviewed journal papers and 62 international and domestic conference papers have been published, and 5 patents been filed.
