Abstract

Based on the characteristics of a thermal imager, a quantitative test method and operational formula of screening rate of infrared screening materials were presented. In this method, a real mode object instead of blackbody was used as a target, which can make the test easy and quick. The screening effect can be measure quantitatively and visually simultaneously. The outfield experiment results conform to each other very well, that is, the target can merge in the background at the screening rate above 85%.
