A method for detecting differences in surface properties of one or more components is provided wherein the infrared radiation emitted by the component at a specific temperature of the component is detected as irradiance on a selected receiver surface relative to the component. When detecting at different positions or on a plurality of components, the solid angle covered by the receiver surface and the distance from the component surface is almost unchanged and differences in the detected irradiance can then be equated with differences in the surface properties of the components. The invention further relates to use of such methods for monitoring and optionally adjusting the surface quality of a component, as well as to a device for adjusting the surface properties in the series production of components.

Generating an accurate and sensitive temperature map over a non-planar surface by capturing a polarimetric thermal image from a non-planar surface. The non-planar surface includes a surface element which emits thermal electromagnetic emission responsive to a temperature of the surface element. Thermal electromagnetic emission is directed to an image element of an image sensor. A polarisation state and intensity are measured of the ray of thermal electromagnetic emission from the surface element. Responsive to the polarization state and the intensity, an angular orientation of the surface element is determined. A temperature of the surface element is determined by estimating the thermal emission normal to the surface element responsive to the angular orientation of the surface element and the intensity of the ray of thermal electromagnetic emission emitting from the surface element.
