dc.description.abstract | Phase-sensitive optical time-domain reflectometry
(φOTDR) is widely used for the distributed detection of
mechanical or environmental variations with resolutions
of typically a few meters. The spatial resolution of these
distributed sensors is related to the temporal width of
the input probe pulses. However, the input pulse width
cannot be arbitrarily reduced (to improve the resolution),
since a minimum pulse energy is required to achieve a good
level of signal-to-noise ratio (SNR), and the pulse peak
power is limited by the advent of nonlinear effects. In this
Letter, inspired by chirped pulse amplification concepts, we
present a novel technique that allows us to increase the SNR
by several orders of magnitude in φOTDR-based sensors
while reaching spatial resolutions in the centimeter range.
In particular, we report an SNR increase of 20 dB over the
traditional architecture, which is able to detect strain events
with a spatial resolution of 1.8 cm. | en |
