OPTICAL DEVICE FOR DETERMINING THE DISPLACEMENT RELATIVE TO EACH OTHER OF HOLES OF ADJACENT SURFACES Russian patent published in 2021 - IPC G01B11/14 G01B11/27 

FIELD: experimental aerodynamics.

SUBSTANCE: invention relates to the field of experimental aerodynamics and can be used when conducting research in transonic wind tunnels with perforation of the test section. Disclosed is an optical device for determining the distance between the holes of adjacent surfaces displaced relative to each other, containing a housing consisting of front and rear sides, an optical system, illumination, a measuring scale, while the device additionally has a video camera installed in the rear part of the housing, the front part of the housing is cylindrical with an outer diameter equal to the diameter of the holes of the surface closest to the device, and the optical system contains a set of lenses for forming a clear image of the measured holes on the video camera.

EFFECT: device that allows quickly measuring the displacement of holes in the plates of perforated panels with fixing the measured values in the memory of a computer device for subsequent information processing.
