Abstract
In a device for detecting excessively heated components or locations in moving objects, in particular in moving rail vehicles, such as bearings, brakes and/or wheel rims, having at least one infrared beam detector (7) and optical devices for representing the image of the measuring point on the infrared beam detector (7), a separate lens (1, 2) is aimed toward each measuring point, which focuses the image of the measuring point on different points (4, 5) of an image-correcting system (3), and a scanning device (9), which periodically picks up the measuring beams, is disposed between the image-correcting system (3) and the detector (7) and focuses the measuring beams onto the detector (7) which is common to all measuring points.
