Multispectral imaging

Definition

Multispectral imaging is a technique that captures image data at specific wavelengths across the electromagnetic spectrum, enabling the analysis of different materials and biological tissues. This method enhances the ability to differentiate and identify various substances based on their spectral signatures, providing valuable information about their composition and properties. The integration of multispectral imaging in diffuse optical imaging allows for deeper insights into tissue characteristics, improving diagnostic accuracy and monitoring capabilities.
