Ultra-broadband contactless imaging power meter

Knowledge of the spatial and temporal distribution heat flux is great interest for quantification sources. In this work, we describe development a new ultra-broadband contactless imaging power meter based on electromagnetic to infrared technology. This sensor mathematical processing images enable reconstruction both amplitude distributions through wide spectral range The full modeling thermoconverter 3D formalism thermal quadrupoles presented first before deriving reduced model more suitable quick robust inverse processing. method makes it possible simultaneously identify losses source time, best our knowledge. Finally, measurements multispectral sources are discussed, with an emphasis resolution, accuracy capabilities meter.
