WE have investigated the infra-red luminescence (fluorescence) of coal and coal derivatives. Little, if any, visible luminescence is shown by coal except (1) in the presence of fluorescing minerals, ...

The aim of this study was to produce calibration equations between near-infrared reflectance (NIR) spectra and the concentrations of carbon, nitrogen, and phosphorus in heterogeneous material: from ...

An established tool for the authentication and conservation of fine art paintings, Fourier-transform infrared spectroscopy (FTIR) typically requires the removal of small sample sections for analysis.

In this multispectral image of Kumbunbur Creek in the Northwest Territories of Australia, is a solid lesson in why false colour composite schemes are so useful in remote sensing. The colours of a ...
