目前对空间和时间的最佳测量（例如引力波探测器和光学参考腔）依赖于光学谐振器，并且最终受到形成谐振器的反射涂层中的热致波动的限制。我们目前的测量涂层的热噪声在音频波段，并表明，对于一个标准的离子束溅射涂层，噪声的功率谱不具有预期的幂律行为。
The best measurements of space and time currently possible (e.g. gravitational wave detectors and optical reference cavities) rely on optical resonators, and are ultimately limited by thermally induced fluctuations in the reflective coatings which form the resonator. We present measurements of coating thermal noise in the audio band and show that for a standard ion beam sputtered coating, the power spectrum of the noise does not have the expected power-law behavior.
