ICE DETECTOR Russian patent published in 2023 - IPC G08B19/02 B64D15/20 

FIELD: detector means.

SUBSTANCE: signalling and control means used for remote detection of icing of structural elements of various objects. The ice detector consists of a pulse generator, a power amplifier, an optical emitter, a transmitting lens, the first and second polarizers, a control surface for ice deposition, a polarizer rotation device, a receiving lens, a photodetector, an amplifier, the first, second and third detectors, the first, second and third integrators, the first and second threshold devices, the first and second filters, a logic device, a computing device, an icing degree indication unit, an icing degree excess indication unit, an alarm device. The second polarizer is kinematically coupled with the polarizer rotation device. The second polarizer contains N elements, where N is a natural number, polarized orthogonally with respect to its axis of rotation, and N optically opaque shutters, each of which is located in the plane of rotation of the second polarizer between its polarized elements.

EFFECT: increasing the accuracy of the signalling.
