Latest Patents

Kwang Yong Song's latest patents include an optical-fiber-characteristic measuring device and an optical-fiber-characteristic measuring method. These innovations enhance measurement precision by efficiently suppressing noise levels from integrated unnecessary components. The measuring means detects the Brillouin gain of a probe light output from a measurement-target optical fiber while sweeping a frequency difference between the pump light and the probe light. This allows for precise measurement of strain distribution in the optical fiber. Additionally, the optical intensity modulator performs intensity modulation on output light in synchronization with frequency modulation on the light source. This capability enables arbitrary adjustment of the spectrum distribution concerning the frequency of light, leading to improved measurement accuracy.

Another significant patent focuses on extending the measurement range while maintaining high spatial resolution. By completely separating the increment of probe light from noise, the technology eliminates the need for an optical wavelength filter. The method allows for wide frequency modulation of the light source, which does not affect the detection of changes in the probe light. This innovation significantly enhances the measurement range while preserving spatial resolution.
