spectraux

Spectraux is a term used in some scientific and speculative contexts to refer to methods and results that involve spectral analysis combined with spatial or contextual information. In this sense, spectraux can be understood as an umbrella name for techniques that map light’s spectrum across space, producing spectral datasets or imagery that encode both wavelength and location. The word is often described as a neologism derived from the French spectraux, and it lacks a single standardized definition in English-language literature.

In practice, spectraux overlaps with fields such as spectroscopy, multispectral and hyperspectral imaging, and spectro-imaging. Core components include a light source or natural illumination, a spectroscopic detector or array of detectors covering wide wavelength ranges, and data processing that aligns spectral data with spatial coordinates to create maps or 3D representations of material properties.

Applications span remote sensing, geology and mineralogy, agriculture and food quality, medical diagnostics, and art conservation, where knowing how materials respond across wavelengths helps identify composition, moisture content, or stress states.

In culture and theoretical contexts, spectraux has appeared as a concept in science fiction and design discussions to describe devices capable of revealing hidden or non-visible spectral information, such as infrared signatures, fluorescence, or Raman-like signals, integrated into a single instrument.

Terminology varies; for rigorous scientific work, researchers typically specify the exact technique (spectroscopy, hyperspectral imaging, spectro-imaging, etc.) rather than using spectraux as a standardized category.
