Embodiment Construction
[0032] The present invention will be further described below in conjunction with the embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.
[0033] Please see first image 3 , image 3It is a schematic composition diagram of the Brillouin scattering high-precision measurement system in the ultra-short optical fiber of the present invention. As shown in the figure, a high-precision measurement system for Brillouin scattering in an ultra-short optical fiber is composed of a laser 2, and the output direction of the laser 2 is connected to the input end of a fiber coupler 3, and the fiber coupler 3 is connected to the input end of the fiber coupler 3. One output end is connected to one end of the circulator 9 through the first polarization controller 4, the fiber isolator 5, and the detection fiber 6 in turn; the other output end of the fiber coupler 3 is connected to the double Mach through the second polarization...
