Problems solved by technology
[0002] The fiber optic gyroscope is an all-solid-state gyroscope with no moving parts. Its core technology lies in the fiber optic ring technology. Under the acceleration field, the shell and the fiber ring in the fiber ring assembly will be deformed to different degrees, resulting in collision between the fiber ring and the shell. These problems affect the accuracy and stability of the fiber optic gyroscope, thereby limiting its wide application

The invention discloses a device and a method for restraining deformation of a fiber-optic gyroscope ring assembly in an acceleration field. The device comprises a piezoelectric induction laying layer and a piezoelectric driving laying layer; the piezoelectric induction laying layer is laid on the top of a fiber-optic ring shell of the fiber-optic gyroscope ring assembly, the piezoelectric driving laying layer is attached to the circumferential face of the fiber-optic ring shell of the fiber-optic gyroscope ring assembly, the piezoelectric induction laying layer corresponds to the piezoelectric driving laying layer in position, and the piezoelectric induction laying layer and the piezoelectric driving laying layer are both made of piezoelectric crystals. Deformation of the shell of the fiber-optic gyroscope ring assembly is directly inhibited from the structural level, and the environmental adaptability and the data accuracy of the fiber-optic gyroscope ring assembly are improved.
