The Fiber Optic Gyroscope, an instrument that can accurately determine the position of moving objects, plays a vital role in modern aviation, navigation, aerospace and defense industries, and is an indispensable inertial navigation device. Fiber optic gyroscopes are important in all modern navigation fields, through which the position of moving objects can be accurately determined. This device not only improves the accuracy of the navigation system, but also performs well in a variety of complex environments, becoming an indispensable part of the development of modern science and technology.
The Fiber Optic Gyroscope plays a pivotal role in military weapons, especially in missile control systems. It is based on an optical fiber coil, and the light emitted by a laser diode propagates in two directions in the optical fiber, thereby achieving accurate measurement of angular displacement. It helps navigation and control with high precision. This sensitive component provides military weapons with high-precision navigation and control systems, ensuring the accuracy and reliability of weapons.
Compared with traditional mechanical gyroscopes, the Fiber Optic Gyroscope has many advantages. It is all solid-state, has no rotating parts and friction parts, so it has a long life and a wide dynamic range. The fiber optic gyroscope also has instant start capability, simple structure, compact size and light weight. Compared with the laser gyroscope, it does not have the problem of locking, and does not require precision processing of the optical path on the quartz block, which reduces the cost. The fiber optic gyroscope stands out with its high precision, no moving parts and high reliability, and its price is more advantageous.
The key component of the Fiber Optic Gyroscope, the fiber winding ring, is deeply affected by the solid fiber glue. The solid fiber glue is filled in the fiber ring, and its gluing process directly determines the characteristics of the glue ring after curing, which in turn affects the overall performance of the fiber ring. The performance of the fiber winding ring is determined by the glue used and the gluing process, which affects the overall performance of the equipment and must be selected carefully. When selecting glue for the fiber ring, its low viscosity characteristics must be considered to adapt to different gluing methods, such as wrapping, gluing and dipping, and at the same time, it is necessary to ensure that the curing stress is small to avoid interference with the fiber ring.
Fiber Optic Gyroscope detectors work based on the Sagnac effect. They sense and detect the angular velocity changes of the carrier relative to the inertial space by measuring the phase difference between two light waves propagating in opposite directions in the fiber ring. This measurement method has the characteristics of high precision and high stability, which makes fiber optic gyroscope detectors widely used in many fields.
The main functions of fiber optic gyroscope detectors Navigation and positioning: In the fields of aerospace, ships, automobiles, etc., fiber optic gyroscope detectors can provide continuous angular velocity measurement data, and combine with other sensors such as accelerometers to achieve precise navigation and positioning functions.
Attitude control: In autonomous motion systems such as drones and robots, fiber optic gyroscope detectors can monitor and feedback the attitude information of the carrier in real time, provide accurate input signals for the control system, and ensure the stable operation and precise control of the carrier. Earthquake monitoring: The high sensitivity of fiber optic gyroscope detectors enables them to capture the angular velocity changes caused by small deformations of the earth's crust. Therefore, they have potential application value in the field of earthquake monitoring, which helps to warn in advance and reduce earthquake disasters.
