dc.description.abstract | We demonstrate a technique to reduce the sidelobes in optical
pulse compression reflectometry for distributed acoustic
sensing. The technique is based on using a Gaussian
probe pulse with linear frequency modulation. This is
shown to improve the sidelobe suppression by 13 dB compared
to the use of square pulses without any significant
penalty in terms of spatial resolution. In addition, a 2.25 dB
enhancement in signal-to-noise ratio is calculated compared
to the use of receiver-side windowing. The method is tested
by measuring 700 Hz vibrations with a 140 nϵ amplitude
at the end of a 50 km fiber sensing link with 34 cm spatial
resolution, giving a record 147,058 spatially resolved
points. | en |
