A two-beam interferometer with the tuning of the interference pattern period by simulating its rotation

Tunable two-beam interferometer with exact fixation of the interference pattern on a stationary photosensitive sample

“…The presented report is a development of the work [6], which describes an interferometer based on a beam-splitting cube (BSC) with two mirrors and a PSO fixed relative to the BSC. The initial light beam (IB) is directed to the input surface of the BSC by a movable mirror (MM), and its linear and angular displacements are mutually coordinated so that the interference pattern (IP) is in close proximity to the PSO in the entire tuning range of the angle of convergence of PBs.…”
