Abstract (en)
[origin: WO2011128157A1] The present invention discloses an apparatus and a method for assessing an object (1) to be tested by means of thermography, in particular active thermography. The intention is to provide a more accurate and more reliable thermography investigation. For this purpose, the intention is to position the object (1) to be assessed and to locate defects on the object (1) with improved accuracy. The invention is distinguished by the fact that an infrared camera (2) having a lens with a first lens axis (2a) is provided for the purpose of recording at least one thermography light image (4) of the object (1). In addition, a projection unit (3) having a lens with a second lens axis (3a) is provided for the purpose of projecting at least one item of information onto the object (1). In addition, a distributor unit (5) which is positioned with respect to the lens axes (2a, 3a) of the infrared camera (2) and of the projection unit (3) is provided for the purpose of reflecting the lens axis of the infrared camera (2) or of the projection unit (3) into the respective other lens axis in the direction of the object (1) and for the purpose of transmitting or deflecting infrared light from the object (1) to the infrared camera (2) and for the purpose of deflecting or transmitting light from the projection unit (3) the object (1).
