AI Summary

Researchers from Aarhus University and Moesgaard Museum in Denmark have created a low‑cost multispectral imaging system for archaeological sites. The prototype replaces ordinary white light with LEDs at 16 wavelengths, spanning near‑ultraviolet, visible, and near‑infrared light. By illuminating the soil with these varied wavelengths, archaeologists can detect subtle differences between layers that appear similar under normal lighting. The system offers a non‑destructive way to examine subsurface features before excavation begins.
