SCREENING TECHNIQUE OF INFRARED LIGHT Russian patent published in 2008 - IPC C06D3/00 

FIELD: protective facilities.

SUBSTANCE: invention concerns protective devices of objects (for instance, aircraft, land conveyance) against detection and/or definition of exact position by drip from it infrared light. Screening technique of object infrared light against detection, at least by one receive of infrared light includes continuous injecting into air between object and radiation detector forming mass aerosol with forming of object, filled by aerosol, containing emission dispersing particles. Aerosol contains more than 5 wt % of emission dispersing particles, each of them contains, at least one extensive electroconductive section with typical dimensions in mutually perpendicular directions Δx, Δy, Δz, fulfilling conditions K₀Δx≈K₀Δy=Δz, where K₀=100...3000, Δz=0.25λ_min...λ_max, where λ_min...λ_max - range of wavelength of infrared light receiver operating. In the capacity of emission dispersing particles can be used carbon nanotube, carbon nanotube bundles or extensive metal single crystal.

EFFECT: effectiveness increase of infrared light dispersion, drip from object, provides decreasing of mass consumption of mask aerosol, increasing of mask time and increasing of aerosol transmission density.
