A multispectral scanner is a device that captures image data at different wavelengths across the electromagnetic spectrum. Unlike standard cameras that only capture visible light, these scanners can detect infrared and ultraviolet light, allowing for a more detailed analysis of objects and surfaces. This technology is widely used in fields such as agriculture, environmental monitoring, and remote sensing. By analyzing the data collected from various wavelengths, researchers can identify materials, assess plant health, and monitor changes in the environment. The information gathered by a multispectral scanner can be crucial for applications like precision agriculture and land use planning.
