ABSTRACT

Micro-optical gyroscope (MOG) has advantages due to integrated optoelectronic technology, where the ring resonator can be fabricated by optical integrated technique. The MOG is a novel type of angle-velocity sensor, which is small, highly precise, and low cost, and so forth [1,2]. Recently, the three-axis gyroscope has been proposed for measurement of three-axis angular velocity [3,4] based on the inertial navigation systems for various applications. The compensation of gyro error has improved the inertial navigation system (INS), which is an important development in calibration technology [5,6]. The general network architecture, such as star, ring, and bus topology can access from a central control (CC) to subscriber. The ring resonator has been used for various applications [7-10], such as dark-bright soliton conversion, random binary code, tweezers generation, and nanosensing applications. In this chapter, a single ring resonator with two lateral nonlinear ring resonators, which is called a modified add-drop filter (a PANDA ring resonator) is used for the fine adjustment of the micro-optical gyroscope. A new system of MOG network using a micro-embedded system consisting of a PANDA ring resonator and CC is proposed. The star topology is an attractive network [11,12]. Modified star-ring architecture with a self-healing function is used to increase the reliability of the sensing network, where each node can perform three-dimensional measurement of rotation motion. The self-calibration among the four-point probe can also be realized using measurement data, that is, time delay of the four probe signals and each of the side rings. Furthermore, by using the central control, the adjustment and control can be performed for the real-time measurement data in any situation. In application, this technique can be useful for distributed sensors, in which the self-calibration is available, where the fine adjustment of the rotational motion is required.
