How it is done: images in visible light can be described in terms of their red, green and blue components (left). On the right are shown infrared images taken at three different wavelengths, which ...

• Leaf optical properties impact leaf energy balance and thus leaf temperature. The effect of leaf development on mid-infrared (MIR) reflectance, and hence thermal emissivity, has not been ...

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.
