INTERFEROMETER Russian patent published in 2020 - IPC G01B9/02 

FIELD: physics.

SUBSTANCE: invention relates to engineering physics. Interferometer has a laser stabilized in power and wavelength He:Ne, having a magnetooptical insulator installed at its output and 5-coordinate device for setting laser radiation into optical fiber, by means of which it is connected to a fiber-optic light beam splitter, which divides the light beam into the first and second coherent optical channels, each of which comprises series-installed optical fiber polarization controller, phase-shifting element and reference spherical wave source, wherein both phase-shifting elements are connected to two-channel controller. Interferometer also has a recording device with two digital video cameras, optically coupled with a source of a reference spherical wave of the first coherent optical channel, and 5-coordinate table at the output of the interferometer for setting up a wavefront corrector.

EFFECT: technical result consists in creation of compact interferometer with possibility of its use with both horizontal and vertical orientation of optical axis, which allows more efficient performance of its functions.
