Paper Abstract

This work describes a new technique that can be used to determine the IR transmittance and path radiance of an obscuring atmosphere. The method is based on alternate measurements of contrast through a clear and obscuring atmosphere respectively. An advantage of this technique is that it utilizes existing thermal imagers and does not require an additional transmissometer in the field. The technique was tested using an AGEI4A 780 Thermovision camera operating in the 7.7-13.2 micron spectral region. A good agreement between theory and the experimental results was obtained.
