  • Abstract
    The optimized intensity modulation is applied to Brillouin Optical Correlation Domain Reflectometry in order to modify optical power spectrum of the light source for suppressing the noise floor in Brillouin Gain Spectrum. The noise level suppression is experimentally demonstrated, and the performance of distributed strain measurement is much improved.
