Non-linear interactions with backscattered light
A system 300 for measuring vibration in a structure comprises first and second lasers 302, 308 that each launch pulses of light of first and second frequencies into a first end of an optical fibre. Backscattering from within the fibre is processed to determine the vibration in the structure. The sys...
