作者报告了位于新西兰基督城开司米洞穴地下30米处的一个非常大的环形激光器的几何比例因子的波动。温度和气压的变化引起腔体的热弹性变形，从而导致环形激光器结构的面积和周长发生变化。现场光束监测已被用来部分纠正这些影响。
The authors report on fluctuations of the geometric scale factor of a very large ring laser situated 30m underground in the Cashmere Cavern in Christchurch (New Zealand). Variations in temperature and atmospheric pressure cause thermoelastic deformations to the cavern, which lead to changes of the area and perimeter of the ring laser structure. In situ beam monitoring has been used to partially correct for these effects.
