在过去的十年中，大环形激光测量地震引起的地面旋转的能力已经显示出它们对地震学领域做出贡献的潜力。不幸的是，像许多光学仪器一样，环形激光器往往很昂贵。在本技术说明中，我们研究了部署成本相对较低的环形激光地面旋转传感器的一些设计选项。对所有有源环形激光器的设计参数进行了审查，然后对目前在阿肯色州康威市外运行的环形激光器中采用的一种特定的相对低成本方法进行了检查。文章最后对该仪器探测到的一些地震进行了讨论。
During the last decade the ability of large ring lasers to measure seismic induced ground rotation has demonstrated their potential for making contributions to the field of seismology. Unfortunately, ring lasers like many optical instruments tend to be expensive. In this technical note, we examine some design options for deploying a relatively low cost ring laser ground rotation sensor. A review of the design parameters, common to all active ring lasers, is followed by an examination of a specific relatively low cost approach currently employed in a ring laser that has been operating outside Conway, Arkansas. The article concludes with a discussion of some earthquakes detected by this instrument.
