Abstract: Disclosed is an IR measuring instrument (1) comprising a least one sensor element (29) which is sensitive to infrared radiation and generates an output signal (12) that depends on the radiation incident on the at least one sensor element (29). The output signal (12) for a predefined incident radiation can be varied by means of an integration time. The actual temperature prevailing on the at least one sensor element (29) is detected and is used for varying the integration time in such a way that the integration time compensates the influence of the temperature variations on the output signal (12) of the at least one sensor element (29).

Abstract: In a thermal imaging camera for acquisition of thermographic images of a measurement object, an electronic evaluation unit is integrated into the thermal imaging camera; it is designed for recognition of corresponding partial regions of the acquired thermographic images, and with it, the acquired images can be assembled into an overall image by overlapping the corresponding partial regions and displayed. The acquisition of the images preferably takes place during the swiveling of the thermal imaging camera over the solid angle region of the desired overall image.

Abstract: In a temperature measuring device (1) an IR-radiation detector (2) and a reference element (3) are provided, connected to a surface (6) of an object (7) in a heat-conducting fashion, with a first area (4) with high emissivity and a second area (5) with high reflectivity formed at the reference element (3), and the IR-radiation detector (2) is equipped for a separate detection of IR-radiation (9, 10, 11) from the first and second areas (4, 5) and a surface area (12) of the object (7). A computer (13) in the IR-radiation detector (2) is equipped to deduct a temperature measurement for the object (7), corrected for emissions and reflections from the detected IR-radiations (9, 10, 11).

Abstract: A method for a touchless determination of the temperature of an object (13) in which at least one IR-image (10) and at least one VIS-image (12) of the object (13) are generated with an IR-detector unit (2) and with a VIS-detector unit (3) of a thermal imaging camera (1), a feature detection (16) is applied to the IR-image (10) and/or the VIS-image (12), thus extracting features (17), and identifying the object (13) from the features (17) extracted and present as a result of the feature detection (16), and to determine and display from the IR-image (10) at least one temperature value (25) of the object (13).

Abstract: The invention relates to a thermographic camera comprising at least one infrared radiation detector and at least one adjusting device that supplies control and/or supply voltages required for operating the thermographic camera. In order to design a thermographic camera in which the temperature-induced drift of the electronics can be compensated while the cost of parts is reduced, a storage medium in which at least one temperature-related characteristic curve is stored is provided on the thermographic camera, and the thermographic camera automatically compensates a temperature-induced drift of the at least one adjusting device on the basis of the characteristic curve. The invention further relates to a method for operating such a thermographic camera.
