Selective solar absorbent coating and manufacturing method, with solar absorption and low emissivity properties. The coating comprises a substrate () of metal, dielectric or ceramic material, at least one highly reflective metal layer () in mid-far infrared applied to the substrate itself which provides low emissivity properties, a mufti-layer structure of alternating dielectric and metallic layers () of subnanometric thickness applied to the reflective metal layer and at least one dielectric layer () that acts as an anti-reflective layer for the solar spectrum. The coating is applicable as a selective absorbent coating in absorbent tubes for parabolic-trough solar collectors, in solar panels for hot water, heating or domestic cooling, both in the form of absorbent tubes and absorbent sheets, in capture systems in tower solar thermoelectric power plants, and in capture systems in Stirling disk systems.

Selective solar absorbent coating and manufacturing method, with solar absorption and low emissivity properties. The coating comprises a substrate () of metal, dielectric or ceramic material, at least one highly reflective metal layer () in mid-far infrared applied to the substrate itself which provides low emissivity properties, a multi-layer structure of alternating dielectric and metallic layers () of subnanometric thickness applied to the reflective metal layer and at least one dielectric layer () that acts as an anti-reflective layer for the solar spectrum. The coating is applicable as a selective absorbent coating in absorbent tubes for parabolic-trough solar collectors, in solar panels for hot water, heating or domestic cooling, both in the form of absorbent tubes and absorbent sheets, in capture systems in tower solar thermoelectric power plants, and in capture systems in Stirling disk systems.

Selective solar absorbent coating and manufacturing method

The present invention relates to a system and method for measuring a wavelength-resolved state of polarization, for calculating differential group delay of an optical signal under analysis () by means of taking multiple measurements of the spectrum of the signal under analysis () with spectral filtering means () with an optical output the power of which depends on the polarization of the input. The polarization at the input of the spectral filtering means () is modified by means of a polarization transformer () which sequentially selects a plurality of output states of polarization. The spectral filtering means () can comprise a filter based on stimulated Brillouin scattering amplification () simultaneously combining wavelength discrimination and polarization discrimination.
