Hyperspectral Sensor
Optical Sensors divided into 3 basic classes: Panchromatic, Multispectral, and Hyperspectral.
Multispectral Sensor typically collects a few, wide (100-200 nm), and possibly noncontiguous spectral bands. Hyperspectral sensors typically collect hundreds of narrow (5-20 nm) contiguous bands. The name hyperspectral implies that the spectral sampling exceeds the spectral detail of the target. In practice, this is not always fully achieved, particularly for gaseous spectra.

Hyperspectral imaging collects and processes information from across the Electromagnetic spectrum
