我们测量表面的热起伏光谱的液体，固体，复杂的流体，和生物物质使用反射光测量下降到倾斜或垂直位移。随机热波动描绘从子散粒噪声水平的随机噪声。测量原理不限于表面测量。表面性质的动态演化也进行了研究。测量时间短、无源，适用于各种表面。
We measure surface thermal fluctuation spectra of liquids, solids, complex fluids, and biological matter using reflected light measurements down toin inclinations orin vertical displacement. The random thermal fluctuations are delineated from random noise at sub-shot noise levels. The principle of the measurement is not limited to surface measurements. The dynamical evolution of the surface properties is also investigated. The measurement time is short, passive, and applicable to a wide variety of surfaces.
