Researchers have developed a cutting-edge tool that uses drone-mounted hyperspectral sensors to detect forensic evidence—such as bloodstains, sweaty clothing, and human skin tones—by analyzing how they reflect light. This technology could drastically improve crime-scene mapping and search-and-rescue operations by allowing teams to scan vast areas quickly and efficiently. By building a spectral data library, scientists can now mix reflective signatures to identify targets, such as a lost hiker’s clothing among rocky terrain or a wounded person in a desert. The system can even differentiate between human and animal remains in dense forests or detect whether soil stains are from blood or fuel.
