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.

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...

The Bidirectional Reflectance Distribution Function (BRDF) provides a quantitative means of characterising how light is reflected from a surface. It is defined as the ratio of radiance scattered by ...

Over the last twenty years, ultrafast laser-based time-domain thermoreflectance (TDTR) has developed as a dependable, efficient, and adaptable approach for measuring the thermal characteristics of a ...
