Glossary

A Short-Wave Infrared (SWIR) sensor is an optoelectronic device that detects radiation in the 1000–2500 nm wavelength range.

Signal-to-noise ratio (SNR) is a measure that compares the level of a desired signal to background noise.

Spatial resolution refers to the ability of an imaging system to distinguish between two closely positioned objects or points. It determines the level of detail an imaging system can capture and represent.

A spectral cube is a three-dimensional data structure that combines spatial information (x and y coordinates) with spectral information for each point in a two-dimensional image.

Spectral imaging is an advanced technology that combines conventional imaging with spectroscopy to capture both spatial and spectral information from an object or scene.

A spectral signature represents the unique pattern of electromagnetic radiation reflected, absorbed, or transmitted by a material across different wavelengths of the electromagnetic spectrum.
