抄録

We review coding techniques for fiber-optic distributed strain and temperature sensors, Brillouin Optical Time Domain Analysis (BOTDA) and Brillouin Optical Time Domain Reflectometry (BOTDR), based on stimulated and spontaneous Brillouin scatterings. The straightforward employment of previous coding techniques fails to enhance signal-to-noise ratio with high spatial resolution. The failure is caused by acousticwave damping effects which involve in the Brillouin scatterings. We show that both the advantageous use and the reduction of the acoustic damping effects lead to successful and efficient implementation of coding techniques to high spatial resolution fiber-optic Brillouin sensors.
