ABSTRACT:
The invention relates to a method and to a device (1) for testing materials by determining and displaying as an image temperature differences above a threshold value on the surface of test objects (8). In a first step, a camera for determining and displaying as an image the temperature differences above a threshold value is used to determine the temperatures of object elements (22) within a test area (14) of the test object (8) facing the camera. The test area (14) is then provided with heat by beam (4) in such a manner that the temperature of the surface of the test object (8) rises in the test area (14) by at least of the threshold value. The object elements (22) are displayed as image elements in such a manner that the temperature differences above the threshold value between the object elements (22) are visible. The cool-down of the test area (14) is indicated by means of the image elements (20).
