Gyroscope Technology and Applications: A Review in the Industrial Perspective
This paper is an overview of current gyroscopes and their roles based on their applications. The considered gyroscopes include mechanical gyroscopes and optical gyroscopes at macro- and micro-scale. Particularly, gyroscope technologies commercially available, such as Mechanical Gyroscopes, silicon MEMS Gyroscopes, Ring Laser Gyroscopes (RLGs) and Fiber-Optic Gyroscopes (FOGs), are discussed. Th...
متن کاملThe Development of Micromachined Gyroscope Structure and Circuitry Technology
This review surveys micromachined gyroscope structure and circuitry technology. The principle of micromachined gyroscopes is first introduced. Then, different kinds of MEMS gyroscope structures, materials and fabrication technologies are illustrated. Micromachined gyroscopes are mainly categorized into micromachined vibrating gyroscopes (MVGs), piezoelectric vibrating gyroscopes (PVGs), surface...
متن کاملEvaluation of Ring Laser and Fiber Optic Gyroscope Technology
In past years much interest has been shown in the development of optical gyroscopes which offer the potential of solid state, highly reliable performance immune from many of the mechanical effects which restrict the performance of conventional spinning mass gyroscopes. Both ring laser and fiber optic gyros operate by sensing the difference in propagation time between beams of light traveling in...
متن کاملPerformance comparison of slow-light coupled-resonator optical gyroscopes
We investigate the connection between group velocity and rotation sensitivity in a number of resonant gyroscope designs. Two key comparisons are made. First, we compare two conventional sensors, namely a resonant fiber optic gyroscope (RFOG) and an interferometric fiber optic gyroscope (FOG). Second, we compare the RFOG to several recently proposed coupled-resonator optical waveguide (CROW) gyr...
متن کاملTechnical Article
Fiber optic gyroscopes (FOGs), previously the low cost equivalent to other technologies such as ring laser gyroscopes (RLG), have some fresh competition. Microelectromechanical system (MEMS) gyroscopes are beginning to take market share away from traditional FOG applications. Specifically, antenna array stabilization, agricultural machine control, and general vehicle navigation are the battlegr...
