Design Analysis and Characterization of the Resonant Optical Gyroscope with a Reflector using Novel Techniques for Performance Enhancement

Abstract

Gyroscopes have been the integral part of various applications ranging from space newlinelaunch and navigation to defense and consumer electronics, since they measure absolute angular velocity of a rotating object. Amongst these, fiber optic gyroscopes newline(FOGs) have been the most popular technology over the last three decades, due to newlinethe advancements in lasers, low loss optical fibers and optoelectronics. Sophisticated newlinemonitoring tools, choice of key optical components and gaps in the other technologies have been prompting new ideas and improvisation techniques to make FOGs newlinean infallible technology. Angular rate measurements are mainly accomplished using two methods viz. interferometry and resonance enhancement. Gyroscopes that newlineutilize the former are known as interferometric fiber optic gyroscopes (IFOGs) and newlinethose that use the latter are resonant fiber optic gyroscopes (RFOGs). newline
