Researchers developed an integrated Brillouin laser ring gyroscope that measures rotation as slow as 37 degrees per hour. This image shows a conceptual schematic of the chip-based gyroscope. Researchers have developed a chip-scale optical ring-laser gyroscope that can measure rotation as slow as 37 degrees per hour. This record sensitivity, approaching Earth's rotation rate of 15 degrees per hour, could eventually be useful for precision navigation and orientation systems, particularly where GPS is unavailable. Gyroscopes measure how an object rotates, helping determine its orientation and movement.
