Why it matters internationally

ONERA’s DOTA department institutionalizes the optical-properties measurement chain for French aerospace research: a dedicated laboratory (MELOPEE) measures spectral and polarized optical properties of materials, coatings, and paints, and the results are capitalized in the MEMOIRES thermo-optical database that feeds infrared signature modelling. For the emissivity community it is a reference for the data-infrastructure face of radiative-property work.

Scope of activity

Quantities: spectral reflectance · polarized optical signatures of coatings and paints · infrared signatures
Spectral range: infrared detector characterization 1–20 µm; optical properties from visible to IR
Methodology: Measurement of optical properties of materials at the MELOPEE laboratory (spectral and polarized signatures of coatings and paints); results capitalized in the MEMOIRES thermo-optical properties database; radiative-transfer code MATISSE for IR signature studies.

Application domains: infrared signature modelling (defense and aerospace) · coating and paint characterization.
