Thermal emittance or thermal emissivity is the ratio of the radiant emittance of heat of a specific object or surface to that of a standard black body. Emissivity and emittivity are both dimensionless quantities given in the range of 0 to 1, but emissivity refers to a material property (of a homogeneous material), while emittivity refers to specific samples or objects.
Handheld multi-sensor device for detecting vehicle paint quality, recoating, dents, corrosion, and estimating the relative age of damage.
ActiveDE202026101327U1Optically investigating flaws/contaminationUsing optical meansSensor fusionHand held devices
Handheld multi-sensor diagnostic device for non-destructive testing of vehicle body surfaces, including: • a handheld device; • an infrared sensor module configured to detect fluctuations in thermal emissivity; • a paint thickness measurement module configured to measure coating thickness; • a surface deformation detection module configured to detect dents and geometric irregularities; • a corrosion detection module configured to identify oxidation features; • an electronic processing unit configured to receive and analyze measurement data from the sensor modules; • a display interface configured to show diagnostic results; wherein the processing unit performs a sensor fusion analysis to produce a consolidated assessment of repainting, dent severity, presence of corrosion, and relative age of damage.
