Abstract
The signal noise ratio (SNR) enhancement of spontaneous Brillouin scattering spectrum on Brilloluin optical time domain reflectometry (BOTDR) sensing system have been demonstrated experimentally through changing the pulse shape. With the same pulse width, the SNRs of the coherent detection power spectrum for trapezoidal pulse and triangular pulse increase relative to that of rectangular pulse. The sensing distances are also increased. This will be helpful to improve the spatial resolution or achieve longer sensing distance in the BOTDR sensing system.
