Visual and Near Infrared Mass Extinction Coefficient of Five Pyrotechnic Screening Smokes

Matti Harkoma Abstract: The screening properties of five different obscurants were compared at relative humidities of 30%, 50% and 85% and mass extinction coefficients were calculated. The obscurants were five military smokes: 1) a traditional hexachloroethane, Zn powder and TNT based screening smoke, the HC smoke as a reference, 2) a potassium chlorite, Mg powder …
