Abstract
Dual-band uncooled Focal Plane Array (FPA) thermal imaging system adopts an Archimedes spiral cord chopper and a matched dual-band light filter to achieve two single-band IR images in one imaging system. Traditional methods of getting two bands images need two single-band thermal imagers, this system only needs one detector and one optical imaging system, so the system's structure becomes smaller and the cost can be reduced. This paper studies the dualband light filter and the realization of capturing dual bands images, it also researches the algorithm of dual-band temperature measurement, using this algorithm, two bands infrared images can be fused into a temperature image.
