New chip-scale gyroscope measures rotation with unprecedented sensitivity

Researchers have developed a chip-scale optical ring-laser gyroscope that measures rotation as slow as 37 degrees per hour, offering a nearly 2,000-fold improvement in sensitivity over previous chip-based versions and using standard CMOS fabrication methods. This technology could enable precise navigation and orientation in environments where GPS is unavailable, with potential applications in cars, aircraft, and spacecraft.
