3D imaging to capture a digital map of an artifact can utilize multiple technologies, but among the options provided, the most relevant would likely be:
2. Laser Technology
Laser scanning technologies, such as LiDAR (Light Detection and Ranging), are commonly used to create detailed 3D models of objects by measuring the time it takes for laser beams to reflect back from the surface of the artifact. This method captures the precise geometry and details of the artifact's surface.
Other methods like electromagnetic radiation and color spectrum imaging can also be valuable in some contexts, but for specifically creating a 3D digital map, laser technology is the most direct and widely used approach. Photography can be used for 2D imaging, but it alone does not create a true 3D map unless combined with other techniques.
