This paper proposes a multi-bus fiber-optic sensor network, which could multiplex different types of fiber sensors, locate the failure position, and recover the sensing services of sensors in a network immediately and automatically to keep them working without being interrupted. It is composed of master and slave nodes, as well as working and backup fibers connecting them. We introduce the operation...
This paper presents a dual mode oscillation control loop design for a solid-state hemispherical resonator gyroscope (HRG) which uses the hemispherical vibrating shell for detecting the Coriolis force. A desirable control loop needs to be robust, fast, and also to have small driving and frequency noises which may cause significant errors, such as angular random walk. To design a fast and robust oscillation...
