This article reports on a study in which chemical contrast was observed in thermal images of blood-stained fabrics exposed to steam.

Abstract

Although thermal imaging is not ordinarily a good way to visualize chemical contrast, the reported study observed strong and reproducible images with chemical contrasts on blood-stained fabrics, especially on more hydrophobic fabrics like acrylic and polyester. (publisher abstract modified)
