Mesure de température par radiométrie multispectrale sans information sur l'émissivité: de promesses en désillusions

Key Points

• Temperature measurements showed inconsistencies when emissivity values are not considered, suggesting viable but flawed methods.
• Key evidence highlights a significant deviation in accuracy, with specific error metrics identifying challenges in reliable assessment.
• Analysis using multispectral radiometry illuminates the impact of ignoring emissivity on temperature results, thereby complicating interpretations.
• This underscores the need for re-evaluation of radiometric techniques, as continued reliance on this approach may limit progress in thermal assessments.
