DEVICE FOR DETECTING NON-HOMOGENEITIES ON FLAT FACES OF CONDUCTING SIMILAR PRODUCT FLOW IN INFRARED RADIATION Russian patent published in 2017 - IPC G01J3/00 

FIELD: physics.

SUBSTANCE: device comprises a source of p-polarized monochromatic radiation, two elements of converting radiation into PEW, a radiation receiver disposed in the environment on the incidence plane, and a measuring device registering the electrical signals incoming from the receiver. Herewith both converting elements are formed as segments of the cylinders, the central angle of which is not less than 45°, the axis are oriented perpendicular to the incidence plane, and the convex surfaces are capable of directing the PEW and have an arc length in the cross-section less than the PEW propagation length.

EFFECT: reducing the duration of measurements and improving their accuracy.
