Hyperspectral imaging merges the capabilities of imaging and spectroscopy, allowing for the capture and processing of extensive spectral information across numerous narrowband wavelengths. By leveraging this technology, detailed spectral analysis can be performed, making it invaluable in applications requiring precise material identification and analysis.
Short-Wave Infrared (SWIR)
SWIR refers to the spectral range between 1 and 3 micrometers (1000-3000 nm). Unlike visible light, which also reflects off surfaces, SWIR’s interaction with different materials reveals distinct spectral characteristics. This makes SWIR imaging particularly useful for identifying and analyzing substances based on their unique spectral signatures. SWIR is capable of penetrating materials and has specific absorption traits, making it different from other imaging technologies. For instance, SWIR’s strong absorption by water molecules enables it to effectively detect moisture content in various materials, such as food products, plants, and other organic matter.
