Ring laser gyros, or RLGs, use a closed ring of light to measure angular acceleration. ... Hemispherical Resonator Gyroscopes A cutaway showing the mushroom-shaped resonator inside an HRG.

This is part of the internal resonant component of a Hemispherical Resonator Gyro (HRG). It generates an electrical field that causes the cup-shaped resonator to vibrate at a specific frequency. An ...

Northrop Grumman Corporation’s (NYSE: NOC) patented hemispherical resonator gyro (HRG) technology, which is used for military and commercial space applications, recently achieved a major ...
