Abstract: A heater and a swing blade device are provided. The heater includes a housing having a first end and a second end arranged in opposite. The housing includes an end wall, a first side wall, and a second side wall; the end wall is disposed at the first end, the first side wall and the second side wall are both located between the first end and the second end; and the first side wall is provided with an air outlet communicating with interior of the housing. A heating component is arranged inside the housing; a first support assembly is provided on the end wall to support the heater when the heater is in a first state; and a second support assembly is provided on the second side wall to support the heater when the heater is in a second state that is different from the first state.

Abstract: 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.
