Number of Bands:
Multispectral Imagery: Captures data in a limited number of broad spectral bands, typically ranging from 3 to 10 bands.
Hyperspectral Imagery: Captures data in a large number of narrow, contiguous spectral bands, often exceeding 100 bands.
Spectral Resolution:
Multispectral Imagery: Lower spectral resolution, as each band covers a wider range of wavelengths.
Hyperspectral Imagery: Higher spectral resolution, with each band covering a very narrow range of wavelengths, allowing for more detailed spectral information.
Data Volume:
Multispectral Imagery: Generates less data, making it easier to process and store.
Hyperspectral Imagery: Generates a large volume of data, requiring more advanced processing and storage capabilities.
Applications:
Multispectral Imagery: Commonly used in applications like agriculture, forestry, and land use mapping where broad spectral information is sufficient.
Hyperspectral Imagery: Used in more specialized applications like mineralogy, medical diagnostics, and environmental monitoring where detailed spectral information is crucial.
Light Collection:
Multispectral cameras collect light from the scene using a lens, similar to conventional cameras.
Spectral Filtering:
The collected light is passed through a series of spectral filters or a filter wheel. Each filter allows only a specific range of wavelengths (spectral band) to pass through.
Image Sensors:
The filtered light is then captured by image sensors, typically CCD or CMOS sensors, which convert the light into electrical signals.
Band Separation:
Each spectral band is captured separately, resulting in multiple images, each corresponding to a different spectral band.
Data Processing:
The captured images are processed and combined to create a multispectral image. This involves calibrating the data, correcting for any distortions, and aligning the images from different bands.
Analysis:
The multispectral image is analyzed to extract information based on the spectral properties of the objects in the scene. This can involve techniques like vegetation indices, material classification, and change detection.
By capturing and analyzing data across multiple spectral bands, multispectral cameras provide valuable information that is not available from conventional imaging systems.
