Evaluating smoke screens' masking ability in infrared using thermovision equipment

摘要

In the process of development new chemicals to be used for generating smoke screens, a method for evaluating the masking ability for the IR spectral domain was needed. The experimental set-up, involving a thermovision equipment and a reference body is presented. The experiments were carried out for different types of chemical mixtures, both in laboratory and field conditions and the attenuation coefficients were calculated. The relevant thermal images, processed using dedicate software, are also presented.
