Interferometric Measurement of Small Refraction Angles.

Abstract

Radial and axial refraction angles are separately measured for rays passing through an azimuthally symmetric medium. The fringe slopes from complementary interferograms are used in a derived expression. Shearing interferometry is used in an example. (Author)
