Latest Patents

Wu's latest patents include a Fabry-Perot (F-P) sensor for measuring inclination. This sensor is designed to be fixed on a static detected object, where a mass block is flexibly connected to a top plate. The configuration ensures that the line between the center of gravity of the mass block and the connecting point on the top plate remains perpendicular to the horizontal plane. This setup creates a Fabry-Perot cavity between a reflecting surface at one end of the mass block and the end of an optic fiber. When the detected object tilts, the cavity length varies, allowing for precise measurement of the tilting angle.

Another significant patent by Wu is the Fabry-Perot (F-P) sensor with a sliding block having an inclined reflective surface. This invention comprises a housing, measuring probe, longitudinal sliding block, and a displacement converting device. The optic fiber extends through a sealing ring and into a hole, with the end surface positioned at the bottom. The longitudinal sliding block features a reflecting surface, forming a Fabry-Perot cavity. The displacement converting device translates lateral slides of the measuring probe into movements of the longitudinal sliding block, altering the distance from the reflecting surface to the fiber end surface. This innovation allows for accurate calculations of the sliding distance based on the measured variation in the Fabry-Perot cavity length.
