Abstract

The distribution of temperature-induced changes in Brillouin frequency shift and that of birefringence-determined frequency deviation in the spectrum of SBS-generated dynamic grating in a PMF have been measured with 1.2-meter spatial resolution and 110-meter measurement range. Synchronously controlled sinusoidal frequency-modulations are applied into two laser sources that are used for pump (probe) light and readout light, respectively, enabling distributed generation and detection of the dynamic grating.
