The handheld thermal imaging camera has a housing which has at least one infrared detector array composed of a plurality of pixels sensitive to infrared radiation. Summary of the Invention

[0003] The present invention starts from a thermal imaging camera which has a housing, a front support, an infrared structure group for detecting infrared radiation, a visual structure group for receiving visual radiation and at least one cooling element which is at least used for cooling the infrared structure group, wherein the infrared structure group and the visual structure group are basically arranged in the housing. It is proposed that the thermal imaging camera has an arrangement device which is configured to arrange the visual structure group relative to the infrared structure group.

[0004] The present invention provides a thermal imaging camera in which thermal influence can be reduced by arranging the visual structure group relative to the infrared structure group.

[0005] A "thermal imaging camera" refers to a device for non - contact measurement of two - dimensional temperature information of a scene when at least outputting information related to two - dimensional temperature information, for example when outputting one or more temperature descriptions, and the one or more temperature descriptions are advantageously two or more temperature values, temperature distributions or the like. In an embodiment of the thermal imaging camera, the two - dimensional temperature information can exist in the form of a thermal image which consists of a plurality of location - resolved and / or spatially - angularly - resolved temperature measurement values.

[0006] The thermal imaging camera can be configured as a handheld thermal imaging camera. A "handheld" thermal imaging camera should in particular be understood as meaning that the thermal imaging camera can be transported only by means of the user's hand, in particular by means of one hand of the user, without the assistance of a transport device. In particular, the thermal imaging camera can also be guided through space in a handheld manner during the measurement process in a movement freely performed by the user of the thermal imaging camera. The mass of the handheld thermal imaging camera is in particular less than 5 kg, advantageously less than 3 kg and particularly advantageously less than 1 kg.

[0007] The housing can be configured as a shell-type housing having two half-shells. The housing has a handle or a handle area by means of which the thermal imaging camera can be guided by a user. The housing receives at least the essential functional components of the thermal imaging camera. Thus, the infrared structure group and the visual structure group are substantially arranged within the housing. In addition, the front support, the cooling element, and / or the arrangement device can be substantially arranged within the housing. Furthermore, the housing receives at least one control unit, an input device and / or an output device (in particular a display device), an energy supply unit, and an analysis and processing unit. The thermal imaging camera can have at least one operating element which is configured to operate the thermal imaging camera. In addition, the housing can have at least one access opening into which visual radiation and / or infrared radiation can enter.

[0008] The front support can be received by the housing. Here, the front support can enclose the housing relative to the environment. The functional components of the thermal imaging camera can be substantially protected within the housing against environmental influences. The front support has openings for the infrared structure group and the visual structure group. The front support has a receiving portion for the visual structure group. The receiving portion for the visual structure group is configured to at least partially surround the visual structure group. The visual structure group can abut against the receiving portion of the front support by means of an end face. It is possible that the visual structure group abuts against the front support, in particular against the receiving portion of the front support, by means of visual optics. The front support can be manufactured, for example, from a thermally conductive material, such as aluminum.

[0009] The visual structure group includes at least one visual camera for taking at least one image and / or video in the visual spectrum of radiation, an optics for the visual camera, and a circuit board for the visual camera. The visual structure group, in particular the circuit board for the visual camera, is connected to the control unit in terms of signal technology. The optics for the visual camera is configured to refract, converge, and / or focus visual radiation and conduct it to the visual camera.

[0010] In addition, the front support has a further receiving portion. The further receiving portion of the front support can have an adhesive layer or an adhesive pad. The further receiving portion of the front support is configured to receive at least one infrared window and / or a glass plate for the visual structure group. In addition, it is possible that the further receiving portion of the front support receives, for example, a laser and a lens for a light source (such as an LED). In addition, a seal can be applied to and / or adhered to the front support.

[0011] The infrared structure group can have an infrared housing, an infrared sensor, infrared optics, and / or an infrared circuit board.

It is also conceivable that the infrared sensor is configured as a bolometer, in particular a microbolometer. For measuring infrared radiation, the thermal imaging camera has an infrared structure group and an analysis and processing unit. The infrared sensor has a plurality of pixels sensitive to infrared radiation. The infrared sensor detects the infrared radiation radiated in a spatial angular range and projected onto the surface of the infrared sensor, and generates a detection signal based on the detected intensity of the incident infrared radiation. The infrared sensor has a two-dimensional detection surface on the surface facing the scene, and a plurality of pixels sensitive to infrared radiation are arranged on the two-dimensional detection surface. Here, each pixel in the pixels of the infrared detector array can, on the premise of being irradiated with infrared radiation, obtain image information and thereby generate a detection signal. Next, the detection signals provided by each pixel can be used to determine temperature information. In particular, the detection signal of each pixel can be forwarded to the analysis and processing unit of the thermal imaging camera. The detection signal can be analyzed and processed by the analysis and processing unit individually and / or in combination with the detection signals of other pixels. The infrared optics is configured to refract, converge, and / or focus the infrared radiation and conduct it onto the infrared sensor. The infrared sensor can be arranged on the infrared circuit board. Thus, the infrared sensor can be arranged between the infrared circuit board and the infrared optics.

In particular, the electronic components of the analysis and processing unit can be arranged on a circuit board or a printed circuit board, preferably arranged on a common circuit board together with the control unit of the thermal imaging camera for controlling the thermal imaging camera. Additionally, the control unit and the analysis and processing unit can also be implemented as a single component, for example, a single component in the form of a microcontroller. The analysis and processing unit is set to receive, analyze and process the detection signals generated by the infrared detector array, especially the detection signals of the pixels that can be connected to the analysis and processing unit in terms of signal technology, and perform the analysis and processing of the two-dimensional temperature information of the scene based on the detection signals of at least a plurality of illuminated pixels of the infrared detector array.
