本文介绍了粗糙金属表面干涉测量临界角的确定以及流动非均匀介质对干涉测量的影响。为此,在空气中使用具有不同表面粗糙度的不同材料进行测量。此外,流动和折射率波动的水的粗糙表面的干涉图的可测量性的影响进行了研究。因此,当使用小束腰直径进行测量时,纹影和水中的流不会显著影响所观察到的干涉图和临界角。
In this paper, we present the determination of critical angles for interferometric measurements on rough metallic surfaces and the influence of streaming inhomogeneous media on interferometric measurements. For this purpose, measurements using different materials with different surface roughness were performed in air. Further, the influence of both streaming and index of refraction-fluctuant water on the measurability of the interferograms from rough surfaces was investigated. As a result, schlieren and streams in water do not significantly affect the observed interferograms and critical angles, when using small beam waist diameters for measuring.
