Abstract:
1. A method for an IR-radiation-based temperature measurement in an object ( 7 ), comprising contacting the object ( 7 ) with a reference element ( 3 ) in a heat-conducting fashion, with the reference element ( 3 ) having a surface comprising a first area ( 4 ) and a second area ( 5 ), with the first area ( 4 ) having a higher emissivity than the second area, and the second area ( 5 ) having a higher reflectivity than the first area ( 4 ), separately detecting a first IR-radiation ( 9 ) emitted by the first area ( 4 ) of the reference element ( 3 ), a second IR-radiation ( 10 ) emitted by the second area ( 5 ) of the reference element ( 3 ), and a third IR-radiation ( 11 ) emitted by a surface area ( 12 ) of the object ( 7 ), determining at least one measurement each from the IR-radiations ( 9 , 10 , 11 ) detected, and determining an emissivity of the surface area ( 12 ) as well as a portion of the reflected IR-radiation of the object ( 7 ) from the measurements, and at least one of the first area ( 4 ) or the second area ( 5 ) of the reference element ( 3 ) can be identified with an electronic image processor ( 19 ) with an algorithm for detecting at least one of patterns or features in a recorded image ( 15 , 17 ).
