What is an three-axis gyroscope?
1. Working principle of three-axis gyroscope
Three-axis gyroscope: simultaneously measure the position, movement trajectory, and acceleration in 6 directions. Single-axis gyroscopes can only measure the object in one direction. An system needs three gyroscopes, and one 3-axis gyroscope can replace three single-axis gyroscopes. The 3-axis gyroscope is small in size, light in weight, simple in structure, and has good reliability, which is the development trend of laser gyroscopes.
2. Application of three-axis gyroscope
In engineering, a gyroscope is an instrument that can accurately determine the orientation of a moving object. It is an inertial navigation instrument widely used in modern aviation, navigation, aerospace and defense industries. Its development has very important strategic significance for the development of a country's industry, defense and other high technologies. Traditional inertial gyroscopes mainly refer to mechanical gyroscopes. Mechanical gyroscopes have high requirements for process structure and complex structure, and their accuracy is restricted by many aspects. Since the 1970s, the development of modern gyroscopes has entered a new stage. In 1976, Vali and Shorthill of the University of Utah proposed the basic concept of modern fiber optic gyroscopes. After the 1980s, modern fiber optic gyroscopes have developed very rapidly, and at the same time, laser resonant gyroscopes have also developed greatly. Due to the advantages of compact structure, high sensitivity, reliable operation, etc., fiber optic gyroscopes have completely replaced traditional mechanical gyroscopes in many fields and become key components in modern navigation instruments. In addition to ring laser gyroscopes, modern integrated vibration gyroscopes are also developed at the same time as fiber optic gyroscopes. Integrated vibration gyroscopes have higher integration and smaller size, and are also an important development direction of modern gyroscopes.
A gyroscope is a device used to measure or maintain orientation, based on the principle of conservation of angular momentum.
Micro-electromechanical systems (MEMS) are embedded systems that integrate electronic and mechanical components in a very small space. A basic MEMS device consists of an application-specific integrated circuit (ASIC) and a micro-machined silicon sensor. When the user rotates the phone, the Coriolis force causes displacement in the X, Y and Z axes. The ASIC processor senses the displacement of the proof mass through the capacitor plate below it and the finger capacitor located at the edge.
