Multispectral

Part of speech: adjective

Definitions

1. Relating to or involving multiple distinct bands of the electromagnetic spectrum, typically used in imaging technology to capture data at different wavelengths for analysis
2. Pertaining to the use of various spectral bands across electromagnetic radiation ranges to obtain comprehensive information, often applied in remote sensing and scientific imaging
3. Characterizing methods or devices that operate by detecting or processing several spectral regions simultaneously, allowing enhanced detail beyond the visible spectrum through various frequency channels

Etymology: Multispectral is a plain modern compound: "multi-" joined to "spectral," which itself comes from "spectrum," a Latin word for an appearance or image, later used in physics for the band of colours that light splits into. The "multi-" element traces back to the Latin "multus," meaning "many," which is ultimately inherited from an ancient Indo-European root for "much" or "many." The meaning of the whole word is literal: it describes an instrument, camera, or sensor that records images across many separate wavelengths of light, rather than only the visible colours the eye can see. Imaging of this kind lets scientists pick out details, such as the composition of a surface or the health of vegetation, that are invisible in ordinary photographs.

Synonyms: multiband, broadband, multiwavelength, polychromatic, hyperspectral

Antonyms: monochromatic, single-band, single-wavelength, narrowband, unispectral
