A few days ago, the 25th China Aerospace Science and Industry Institute successfully developed a new generation of small-size, high-performance, high-resolution, low-power infrared thermal imaging camera. According to reports, the product has reached the leading domestic level.
In nature, as long as the temperature is higher than absolute zero (-273°C), an object can radiate electromagnetic waves. Infrared rays are the most widespread forms of electromagnetic waves in the natural world. It is an energy, and this energy is what we see with the naked eye. Invisible. Any object in the normal environment will produce its own molecules and atoms moving at random, and constantly radiating out of thermal infrared energy.
Infrared thermal imaging technology is to turn invisible infrared radiation into visible thermal imaging technology. Infrared thermal imaging cameras mainly use infrared radiation that is used to detect target objects, and then undergo photoelectric conversion, electrical signal processing, and other means. The temperature distribution of the image is converted into a video image of a high-tech product.
In the field of industrial automation, infrared cameras can play an irreplaceable role in five applications such as automated inspections, process control, condition monitoring, fire prevention and monitoring, and continuous optical gas imaging. For example, in food production line quality Controlling the windshield defrosting inspection of automobiles, controlling the positioning of pipelines in automatic welding machines, has a very important role in the thermal inspection of high-voltage equipment and hot spot display on the ladle, the possibility of faults, continuous monitoring of warehouses, etc.
Faced with the enormous potential for development of infrared thermal imagers, it has been developed in various fields and the scale of the industry has been continuously expanded. According to incomplete statistics, the potential demand for infrared thermal imaging technology market in China can reach 500 to 60 billion yuan. The current market situation is only in its infancy. By 2020, the infrared imaging market will grow by more than 20%.
Based on the needs of localization, autonomy and market, China Aerospace Science and Technology has innovatively developed a small-scale, high-performance, general-purpose cooling infrared thermal imager based on existing infrared imaging technology. The thermal imager uses high-performance mid-wave focal plane refrigeration infrared detectors. It is highly integrated to drive the imaging circuit. It has excellent features such as high sensitivity, high resolution, and ultra-long distance detection. It also has on-chip non-uniformity correction and blind flash element judgment. Compensation, advanced image processing and other functions, even in the large dynamic range infrared scene, can also output a sharp, sharp image.
This high-performance photoelectric sensor product can be used for security monitoring, intelligent transportation, power safety, forest fire prevention, resource remote sensing and other fields, which will produce significant economic and social benefits.
In recent years, under the background of military-civilian integration, China Aerospace Science and Industry Corporation has launched a number of products based on military-to-civilian technology, and there are already many products that are moving toward application. Currently, the second generation of Chinese Aerospace Science and Technology Corporation is based on the heat of infrared imaging SoC chips. Imager is also under development.
