System Uncovers Hidden Subsurface Artifacts
Danish researchers have developed a low-cost multispectral imaging system based on LED lamps that uses 16 wavelengths to detect buried artifacts underground. The system, through an ICA algorithm, can isolate and identify hidden archaeological sources not visible in traditional images, aiding in the precise discovery of archaeological layers and areas, including bone fragments and changes in the natural terrain. This system is employed at archaeological sites such as the island of Bornholm, and the prototype cost approximately one-tenth of advanced systems, with imaging time reduced to 30 seconds. The technology is quickly becoming an affordable and effective tool for exploring buried artifacts, as researchers continue to improve real-time analysis and machine learning applications.
