Passive, free-space heterodyne laser gyroscope
Laser gyroscopes making use of the Sagnac effect have been used as highly accurate rotation sensors for many years.First used in aerospace and defense applications, these devices have more recently been used for precision seismology and in other research settings.In particular, mid-sized (∼ 1 m-scale) laser gyros have been under …
