Keywords : Red coloured smokes;Target detecting devices;Smokes;Attenuate infrared light
Abstract : The infrared absorbance at wavelength 1.5 - 2.5 micro meter has been studied for white, orange, green and red coloured smokes. This paper describes an experimental set up, the results obtained and also discusses the potential application of smokes in attenuating infrared light assisting opto-electronic target detecting devices.

Abstract : This paper describes the experimental setup for the evaluation of bursting smoke for anti-infrared role using SR-5000 spectroradiometer and a source of IR radiation (8-13 micrometer) using cadmium-mercury-telluride (CMI) detector cooled by liquid nitrogen. The particle size and shape of the powders used in the bursting smokes were determined microscopically using Carl Zeiss Jena Neophot- 21. Highest attenuation of 97 -lOOper cent was produced for about 12 s using a mixture of bronze flakes and chaff, and for about 8 s using a mixture of bronze copper lined flakes, bronze flakes and chaff.
