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.
