What does 'multispectral' refer to in imaging technology?

Multispectral imaging technology involves capturing data at different wavelengths across the electromagnetic spectrum. This approach allows for the analysis of various materials and conditions that cannot be distinguished using standard visible light alone. By utilizing multiple spectral bands, multispectral imaging enables the identification of features such as vegetation health, mineral compositions, and surface moisture, as each material reflects and absorbs light differently across various wavelengths.

The focus on a range of wavelengths is crucial for applications in agriculture, environmental monitoring, and remote sensing, as it provides a more comprehensive understanding of the subject being studied. This capability to discern characteristics based on spectral responses sets multispectral imaging apart from other imaging methods that rely on only a single spectrum or limited wavelengths.
