Latest Patents

One of Yu Liu's latest patents is the "Cavity Optomechanical Vibratory Gyroscope." This invention pertains to the technical fields of resonant optical gyroscopes and micro-optical-electro-mechanical systems. It introduces a novel cavity optomechanical Coriolis vibratory micro gyroscope based on ring micro rings and the Coriolis vibration principle. The driving and detection mechanisms are fundamentally different from conventional electric or magnetic means. By utilizing cavity optomechanical technologies, this gyroscope achieves full-optical driving, detecting, and sensing, which effectively suppresses various noises, including thermal noise and cross interference. Additionally, it obtains displacement sensing information through a linear relationship between frequency shift and light amplitude in the micro cavity optomechanical effect.

Another significant patent is the "Intelligent Rolling Contact Fatigue Testing System and Testing Method Therefor." This system includes a main testing system, a loading system, and a subsidiary testing system. It features a testing device that comprises a light source, a CCD camera, and a monitoring assistance device. During testing, a roller test specimen and a subsidiary testing piece are monitored after being rolled in contact for a certain duration. The CCD camera dynamically collects surface images of the roller test specimen, allowing for quantization evaluation of fatigue failure states through advanced image processing techniques.
