摘要
A ring laser gyroscope (RLG) assembly comprises an RLG block comprising: a first anode; a second anode; a cathode; and a cavity. The RLG assembly further comprises a current supply circuit coupled to the RLG block. The current supply circuit comprises a high voltage power supply to provide a high voltage signal; a first current path coupled between the high voltage power supply and the first anode to provide a first current to the first anode; and a second current path coupled between the high voltage power supply and the second anode to provide a second current to the second anode. The second current path is configured to mirror the first current such that the second current approximately matches the first current. Each component in the second current path is configured to operate based on power derived only from the high voltage signal.
