Limiting characteristics of a rotationally tunable two-beam interferometer with a fixed photosensitive element

Abstract

Results of calculations of the limiting characteristics of a rotationally tunable two-beam interferometer on the basis of a beam-splitter cube with fixed mirrors and a fixed photosensitive element are presented. The convergence angle is changed solely by rotating the beam source with respect to the interferometer. It is shown that the convergence angle can be varied in the interval from 46 to 166° with sufficiently wide light beams.
