Brillouin Phase Spectrum Recovery Based on Kramers-Kronig Relation in Direct-Detection BOTDA Sensors (W6A.43)

Presenter: Keyan Zeng, Huazhong University of Sci. & Tech.

Without the need of coherent detection and hardware modification, Brillouin phase spectrum is digitally recovered for the first time from the Brillouin gain spectrum based on Kramers-Kronig relation in a conventional direct-detection BOTDA sensing system.
