  • Publication number: 20200378762
    Abstract: A gyroscope and method for navigating using the gyroscope can include a substrate that can define a cavity. The cavity can be placed under a vacuum, and a birefringent microrotor can be located in the cavity. A light source can direct light through the substrate and into the cavity to establish an optical spring effect, which act on the microrotor to establish an initial reference position, as well as to establish rotational and translational motion of said microrotor. A receiver can detect light that has passed through said cavity. Changes in light patterns that can be detected at the receiver can be indicative of a change in position of the microrotor. The change and rate of change in position of the microrotor can be used for inertial navigation.
