Abstract
The invention relates to a method of producing a screening smoke which is one-way transparent in the infrared spectrum (780 nm-14.0 &mgr;m) and opaque in the visible spectrum. According to the invention a known pyrotechnic screening smoke which is highly absorbent in the visible spectrum (380 nm-780 nm) is generated in the form of an aerosol, pyrotechnic scattered particles between 10 and 100 &mgr;m in size are simultaneously produced in said aerosol, and the resulting two-component smoke is irradiated by an infrared radiation source (spectrum: 780 nm-14.0 &mgr;m) from the smoke producer side.
