The reported project involved Infrared thermal imaging, using lock-in and molecular factor computing methods for the detection of blood on a dark, acrylic fabric.
Abstract
It noted contrast differences between the clean fabric and the fabric stained with blood diluted as low as 1:100. It also demonstrated that this method can be used to discriminate between a bloodstain and four common interfering agents (bleach, rust, cherry soda, and coffee) to other blood detection methods. These results indicate that this system could be useful for crime-scene investigations by focusing nondestructive attention on areas more likely to be suitable for further analysis.
