RETROGRAPHIC SENSORS Russian patent published in 2022 - IPC G01N21/17 

Abstract RU 2782368 C2

FIELD: image formation.

SUBSTANCE: retrographic sensor includes transparent elastomeric substrate, a deformable reflecting layer, and a contact surface with a matrix of rigid non-flat elements formed of material or with a particle structure for weakening adhesion to an object surface and at the same time for providing a possibility for captured air of releasing from an area of interest.

EFFECT: this combination of elements allows for a contact surface of a sensor for more accurate coordination with an object surface and at the same time physical transmission of topography of the object surface to a deformable layer for the formation of an image through substrate.
