摘要：
The ultra low expansion cavities play a crucial role in laser stabilization, and they are essential in ion clocks. We present a method to measure changes in the distance between mirrors of a Fabry-Perot cavity (FPC) with a spacer from an ultra low expansion material caused by temperature variation with femtometer resolution. The FPC was placed into a temperature-stabilized vacuum stainless steel chamber.
