光纤陀螺的多光源主动抗辐射装置
摘要：
利用多光源实现光纤陀螺主动抗辐射加固装置，其特征在于：在光纤陀螺光路的耦合器输入端接入大功率半导体激光器LD，用于对光纤褪色处理所需要的强光；光纤陀螺的前放输出端接至协调控制电路的输入端，用于对前放输出信号的监测，对陀螺的运转状态做出判断；所述的协调控制电路的输出端分别与光纤陀螺SLD光源和大功率半导体激光器LD相接，用于周期性的启动和关闭大功率半导体激光器LD，同时所述的协调控制电路输出端还与光纤陀螺电路中的信号处理电路连接，用于控制光纤陀螺解调系统的关闭和启动，实现陀螺的主动防护。本发明周期性的防护时间很短，陀螺系统以相对较长的时间工作，保证了输出信号的连续性和准确性。
摘要（英）：

The invention relates to an apparatus for using multi-light source to achieve optical fiber gyrostat active anti-spreading reinforce which is characterized in that it connects a large power semiconductor laser LD on the couple input end of the optical fiber gyrostat light path to process the strong light needed by the fiber optic discolor; the front output end of the optical fiber gyrostat is connected with the input end of the collaborating control circuit to monitor the front output signal and quote the running condition of the gyrostat; the output ends of the collaborating control circuit are separately connected with the optical fiber gyrostat SLD light source and the large power semiconductor laser LD to periodically open and close the large power semiconductor laser LD; the output end of the collaborating control circuit is connected with the signal processing circuit to control the open and close of the optical fiber gyroscope demodulating system to achieve the active prevention of the gyroscope.
