Multi-spectral analysis has the advantage of being able to detect a wider range of materials than an X-ray machine. It can detect materials that are not visible to the naked eye, such as certain types of plastics, explosives, and drugs. It can also detect materials that are not easily detected by X-ray machines, such as certain types of metals and minerals. Additionally, multi-spectral analysis can detect materials that are hidden behind other materials, such as in walls or containers.
