Abstract: In this paper, we present a theoretical analysis and experimental results of a pyrometric temperature measurement method based on a two-color pyroreflectometer (working wavelengths of 1.3μm and ...

Abstract: Devices and methods are presented in which an optical fiber reflectometer and a solar concentrator are used to determine solar reflectivity and absorptivity for opaque and diffuse materials. The ...

Abstract: Despite the existence of several possible pyrometric methodologies, temperature monitoring and control of samples heated at the focus of solar concentrators have still not received a universal ...

Abstract: This paper deals with the material testing under extreme conditions, mainly around space programs, using the French CNRS (Centre National de la Recherche Scientifique) solar facilities for planetary ...
