【Abstract】 China needs to develop her own digital frequency control system of ring laser gyros (RLG). We participated in this effort, and developed a computer controlled automatic mode sweep system, which is one of the key subsystems of the digital frequency control system of RLG. Fig.3 gives the schematic diagram of the computer controlled automatic mode sweep system. The cavity length is changed by changing the voltage of PZT which is controlled by a single chip computer system. The change of the cavity length changes the output frequency of RLG. Compared with the existing mode sweep system, our system is more stable and more reliable, with many new functions such as memory, auto search optimal mode, etc. Test result (Fig.5) shows that our system is successful.更多还原
