TLDR
In this article, the role of integrated optics and photonic integrated circuit technology in the enhancement of gyroscope performance and compactness is broadly discussed, and the architecture of new slow-light integrated angular rate sensors is described.Abstract:
Photonics for angular rate sensing is a well-established research field having very
important industrial applications, especially in the field of strapdown inertial
navigation. Recent advances in this research field are reviewed. Results obtained in
the past years in the development of the ring laser gyroscope and the fiber optic
gyroscope are presented. The role of integrated optics and photonic integrated
circuit technology in the enhancement of gyroscope performance and compactness is
broadly discussed. Architectures of new slow-light integrated angular rate sensors
are described. Finally, photonic gyroscopes are compared with other solid-state
gyros, showing their strengths and weaknesses.read more
