Abstract

ABSTRACT A laser and acoustooptic frequency shifter jointed Pound-Drever-Hall technique is designed to lock the resonant optical gyroscope. Utilizing direct digital synthesizer (DDS) technology and temperature control in the driver, the frequency-shift precision of the acoustooptic frequency shifter higher than 1 Hz is obtained. Experiments show that compared with locking by tuning the laser only, the zero-bias stability of the gyroscope is improved. In this locking scheme, there are few additional devices, the tuning of the laser and the acoustooptic frequency shifter share a common Pound-Drever-Hall locking system, and the demodulation and the locking algorithms are simple.

激光与声光移频器联合Pound-Drever-Hall技术提高谐振光陀螺锁定精度

设计了一种结合庞德-德雷弗-霍尔技术的激光和声光移频器锁住谐振光学陀螺仪。利用直接数字合成器(DDS)技术和驱动器温度控制，实现了声光移频器的移频精度高于1hz。实验表明，与仅通过调谐激光进行锁定相比，陀螺仪的零偏稳定性得到了提高。在该锁定方案中，附加器件少，激光器调谐和声光移频器共用一个庞德-德雷弗-霍尔锁定系统，解调和锁定算法简单。

期刊介绍： Fiber and Integrated Optics , now incorporating the International Journal of Optoelectronics, is an international bimonthly journal that disseminates significant developments and in-depth surveys in the fields of fiber and integrated optics. The journal is unique in bridging the major disciplines relevant to optical fibers and electro-optical devices. This results in a balanced presentation of basic research, systems applications, and economics. For more than a decade, Fiber and Integrated Optics has been a valuable forum for scientists, engineers, manufacturers, and the business community to exchange and discuss techno-economic advances in the field.
