一种谐振式光纤陀螺谐振频率跟踪系统
摘要：
本实用新型属于谐振式光纤陀螺技术，涉及一种谐振式光纤陀螺谐振频率跟踪系统。所述谐振式光纤陀螺谐振频率跟踪系统包括谐振跟踪粗调系统以及谐振跟踪微调系统，所述谐振跟踪粗调系统以及谐振跟踪微调系统分别与激光器的激光驱动相连，且谐振跟踪粗调系统具有一长度以及连接关系与谐振跟踪微调系统内光纤敏感环近似的参考谐振腔。本实用新型采用粗细两路稳频的方法，在系统中引入参考谐振腔进行光纤环谐振频率的粗调，使得激光器与光纤环的频率落入微调稳频电路的范围，这样在保证激光器不脱锁的同时保证频率锁定精度。
摘要（英）：

The utility model belongs to resonant mode fiber optic gyroscope technique relates to a resonant mode fiber optic gyroscope resonant frequency tracker. Resonant mode fiber optic gyroscope resonant frequency tracker includes resonance tracking coarse adjusting system and resonance tracking fine setting system, the coarse adjusting system is trailed to resonance and resonance tracking fine setting system is continuous with the laser -driven of laser instrument respectively, and resonance tracking coarse adjusting system has the approximate reference resonant cavity of the sensitive ring of optic fibre in a length and relation of connection and the resonance tracking fine setting system. The utility model discloses a coarse adjusting of referring to the resonant cavity and carrying out optic fibre ring resonant frequency is introduced to the method of two tunnel frequency stabilizations of thickness in the system for the laser instrument falls into the scope of finely tuning the frequency stabilization circuit with the frequency of optic fibre ring, is guaranteeing to guarantee the frequency locking precision like this when the laser instrument does not take off the lock.
