Latest Patents

The supplied information identifies one patent associated with Xiao: “Self-calibrating optical fiber pressure, strain and temperature sensors.” The invention uses broadband optical energy and a transducer with reflective surfaces separated by a gap. By splitting reflected energy into beams and filtering them through different pass bands, the system produces signals with different sensitivities to changes in the gap. Comparing their power ratio helps cancel variations in source intensity and fiber attenuation, enabling precise measurements. The design can also compensate for physical effects that are not the focus of a measurement and supports sensing over longer lengths of optical fiber. Xiao is credited with 1 patent.
