Latest Patents

One of his key patents is a phase difference calculation method, device, and system using an optical fiber ring interference sensor. This invention involves a 3×3 optical splitting coupler and an optical splitting coupler. It establishes linear sections in advance, where the relationship between the phase difference of propagation lights and the intensity outputted from each photo detector becomes approximately linear. The intensity of interference light, which has a non-reciprocal phase bias, is measured multiple times. A phase difference is then calculated based on the intensity in these linear sections. This innovative approach enhances the precision of measurements in optical fiber systems.
