New multiplexing scheme for monitoring fiber optic Bragg grating sensors in the coherence domain

, 1997
A new multiplexing scheme for monitoring fiber optic Bragg gratings in the coherence domain has been developed. Grating pairs with different grating distances are distributed along a fiber line, and interference between their reflections is monitored ...
