The Integrated Optics Rotation Sensor (IORS) is a rugged, lightweight, and low cost gyro instrument which is currently being sponsored. It uses glass-on-silicon optical waveguide technology. The design of the IORS is quite simple, and can potentially be adapted to a number of military and commercial applications, including yaw rate sensing for an anti-skid safety device in automobiles, rotation rate sensing for robotics, weapon aiming, and guidance of smart munitions. The IORS incorporates a gyro waveguide coil into an advanced integrated optics circuit (IOC). The advanced IOC performs all the key signal processing functions, and in addition, incorporates a unique passive quadrature biasing circuit directly on the integrated optics chip. Therefore, it provides an output with maximum sensitivity similar to a fiber optic gyro, but without the need for an active biasing means. The basic design is presented, along with preliminary performance specifications for an IORS prototype. The characteristics of the IORS is also compared to other gyros in terms of performance, size, weight, and price.
