Problems solved by technology

[0005] For this reason, the present invention provides an infrared thermal imager with high imaging precision. By setting a temperature sensor, the thermal imager detects the temperature in time when the thermal imager is performing thermal imaging on an object with a higher temperature. The temperature control device cools down, and at the same time starts the laser reflector 1 and the laser emitter 2 to generate excitation laser to weaken the thermal radiation, so as to solve the problem that the temperature is too high and affects the thermal imaging accuracy

Description

technical field [0001] The invention relates to the technical field of thermal imaging, in particular to an infrared thermal imager with high imaging precision. Background technique [0002] All objects in nature, whether they are arctic glaciers, flames, human bodies, or even the extremely cold deep space of the universe, as long as their temperature is higher than absolute zero -273°C, there will be infrared radiation, which is due to the thermal movement of molecules inside the object. As a result, its radiation energy is proportional to the fourth power of its own temperature, and the radiated wavelength is inversely proportional to its temperature. Infrared imaging technology is based on the level of radiation energy of detected objects. After being processed by the system, it is transformed into a thermal image of the target object and displayed in grayscale or pseudo-color, that is, the temperature distribution of the measured target is obtained to judge the state of ...
