Patent number: 11415417Abstract: A cavity optomechanical vibratory gyroscope pertains to technical fields of resonant optical gyroscopes and micro-optical-electro-mechanical systems. A novel cavity optomechnical Coriolis vibratory micro gyroscope is realized based on ring micro rings and the Coriolis vibration principle, and driving and detection thereof is completely different from conventional electric or magnetic means. Based on the principle of angular velocity sensitive structures in the conventional Coriolis vibratory gyroscopes, full-optical driving, detecting and sensing of a vibratory gyroscope are achieved using cavity optomechnical technologies, which fundamentally suppresses various noises (including thermal noise, cross interference, connection point noise and quadrature error) introduced by electric or magnetic driving. Besides, displacement (vibration) sensing information is obtained according to a linear relationship between frequency shift and light amplitude in the micro cavity optomechnical effect.Type: GrantFiled: September 25, 2020Date of Patent: August 16, 2022Assignee: CHONGQING UNIVERSITY OF POSTS AND TELECOMMUNICATIONSInventors: Yu Liu, Yongle Lu, Huihui Yang, Ke Di, Xinhai Zou, Zhen Fang, Jijun Bu, Yong Yang, Lele Fu
