Development and Validation of Measurement Techniques of Transmittance of Thermal Contrast Utilizing Existing IR Imagers

Abstract

This work describes a new technique used to measure the transmittance of IR contrast of thermal targets. The advantage of this technique is that it utilizes existing thermal imagers and does not require additional equipment in the field. The technique was tested with an AGA 780 Thermovision camera operating in the 8-13 micron spectral region, on the contrast of a thermal target as it 'propagates' through smoke. An excellent agreement between theory and the experimental results was obtained.
