| 摘要 |
An optical fiber (F) characteristic measuring device of the present invention includes a light source (10), an optical divider (20), an optical waveguide (30), a first separator (60), a second separator (80), a first interferer (90), a second interferer (100), and a calculator (170). The light source (10) is configured to generate a frequency modulated continuous wave of light. The optical divider (20) is configured to divide the frequency modulated continuous wave of light into first and second divided-waves of light. The optical waveguide (30) is configured to guide the first divided-wave of light to one end of an optical fiber to be measured. The first separator (60) is configured to separate a backscattered light generated by Brillouin scattering of the first divided-wave of light in the optical fiber to be measured into a first scattered light, which is a linearly polarized light, and a second scattered light, which is a linearly polarized light perpendicular to the first scattered light. |
