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

Abstract

The invention belongs to the technical field of thermal imaging, and particularly relates to an infrared thermal imager with high imaging precision, which comprises a shell, an imaging device, a temperature control device and a circuit board, the imaging device is fixedly mounted on the inner wall of the shell, the temperature control device is arranged at the top of the imaging device, and the circuit board is fixedly mounted at the bottom of the inner wall of the shell. The imaging device comprises a thermal imaging lens, one-way reflective lenses are arranged below the thermal imaging lens, the one-way reflective lenses are fixedly installed on the inner wall of the left side of the shell, two groups of reflective lenses are symmetrically arranged left and right, and a filter lens is arranged on the right side of the thermal imaging lens and fixedly installed on the inner wall of the shell. A first one-way reflective lens isarranged on the right side of the filter lens. The infrared thermal imager has the beneficial effects that the temperature control device is arranged, rapid heat exchange is carried out according to the thermoelectric refrigeration principle, the temperature in the shell is adjusted to be constant, the thermal imaging result is prevented from being affected by the environment temperature, the thermal imaging precision is improved, and the application range is widened.

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 it is 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 radiant 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 radiant energy of the detected object. After being processed by the system, it is transformed into a thermal image of the target object, which is displayed in grayscale or pseudo-color, that is, the temperature distribution of the measured target can be obtained to judge the sta...
