![]() There are multiple factors that can cause errors in the output of Gyroscopic (Gyro) Sensors. ![]() Other Information on Gyroscopic Sensors 1. In an optical gyroscopic sensor, the light path lengthens as the orbiting light itself rotates, and the angular velocity can be calculated by measuring the phase difference caused by the lengthening. This physical phenomenon occurs because the speed of light is always constant. The Sagnac effect used in optical gyroscopic sensors is the principle that if the optical path through which light passes is in motion, the length of the optical path will increase. Ω=F/2mv (ω: angular velocity, F: Coriolis force, m: mass of object, v: velocity of movement) 2. The relationship between the Coriolis force and angular velocity can be expressed by the following equation. The Coriolis force during rotation generates a difference in the capacitance between the left and right sensing electrodes of the resonator, and the angular velocity is calculated by measuring the Coriolis force from the difference in capacitance. This method measures the voltage value generated in a rotating transducer as a physical quantity corresponding to the Coriolis force. Vibration gyro sensors can be further classified into piezoelectric and capacitive types. The Coriolis force used in vibrating gyro sensors is the apparent force acting on a rotating object as it moves. Gyro sensors are typically classified into two types: vibration type, which uses the Coriolis force to measure, and optical type, which uses the Sagnac effect of light to measure. Therefore, the accuracy of the control of the device using the gyro sensor and the environment in which it will be used must be taken into consideration when selecting a gyro sensor. Gyro sensors have different characteristics depending on the product, such as heat and vibration tolerance and size. Measurement of user movement and position in VR games.Measurement and control of aircraft position.Image stabilization of smartphones and digital cameras.Specific applications of gyro sensors are as follows: Gyro sensors are used in a wide range of applications in the control of smartphones, digital cameras, gaming devices, space industry, aviation, automobiles, and industrial robots. In particular, gyro sensors are always used in fields such as robotics, aircraft, and automobile body control, where feedback control must take into account minute rotations. Angular velocity refers to the physical quantity of rotation of an object per unit of time, and is an indispensable sensor in today's industrial machinery products, where advanced and accurate control is required. It does not store any personal data.A gyroscopic (gyro) sensor is a sensor used to detect angular velocity.
