A PROCESS OF OPACIFICATION OF A GASEOUS MEDIUM IN THE OPTICAL AND INFRARED BANDS OF THE ELECTROMAGNETIC SPECTRUM, AND ITS APPLICATION TO AN ELECTRO-OPTICAL COUNTER-MEASURE DEVICE

摘要

The invention relates to a process for opacifying a gaseous medium transparent to optical and thermal radiation. It is characterized in that it consists in diffusing in the medium, for example the atmosphere, an aerosol such as boron trichloride (BCl3). The invention applies to the field of electro-optical countermeasures.
