INTERFEROMETER FOR CONTROLLING THE SHAPE OF CONVEX HYPERBOLIC MIRRORS Russian patent published in 2018 - IPC G01B9/02 G01B11/24 G01M11/02 

FIELD: measuring equipment.

SUBSTANCE: interferometer contains laser illuminator and objective in the lighting branch, beam splitting cube, optical nodes of the reference and working branches, waveform analyzer in the recording branch. Meniscus concentric lens is mounted above the controlled surface of the convex hyperbolic mirror. Centers of curvature of the spherical surfaces of the lens are combined with the imaginary geometric focus of the hyperbolic mirror surface. Lens has the ability to rotate around the imaginary focus of the monitored mirror.

EFFECT: technical result is the possibility of controlling the shape of extremely large convex hyperbolic mirrors with a diameter of more than 2 m.
