Chip-scale gyroscope measures rotation at record sensitivity
Phys.org
Researchers developed an optical ring-laser gyroscope on a chip that detects rotation as slow as 37 degrees per hour. The technology could eventually support precision navigation and orientation where GPS is unavailable.

Researchers have developed a chip-scale optical ring-laser gyroscope that measures rotation as slow as 37 degrees per hour. Its sensitivity approaches Earth’s rotation rate of 15 degrees per hour.
The device could eventually be used in precision navigation and orientation systems, particularly in places where GPS is unavailable.
