Relationship between uncooled infrared detectors and infrared thermal imagers

With the development of uncooled infrared detectors, the resolution and sensitivity of the final imaging of infrared thermal imager equipment are directly determined. It can help the equipment collect infrared temperature data and thermal distribution information, and use other components to perform imaging to detect the temperature of objects.

As my country's scientific research institutes and military enterprises began to focus on the research and development of infrared thermal imaging. "From upstream infrared thermal imaging detectors to midstream chips and movements, and then to infrared thermal imager complete machines, we have gradually gotten rid of the dilemma of importing important components and technological blockades, and also created a group of high-quality private enterprises with independent and controllable industrial chains."

Infrared thermal imagers can be divided into cooled and uncooled types. At present, the uncooled detectors on the mainstream market have basically been domestically produced, and the domestic uncooled detector technology is at the international leading level.

Refrigerated infrared thermal imagers need to work in ultra-low temperature environments, and have the characteristics of high sensitivity and long range, good concealment, strong anti-interference and strong target recognition capabilities. They are usually used in high-end military fields such as aerospace, ships, missiles, and scientific research. At present, a very small compressor that can quickly reduce the surface temperature of the detector to minus 200℃ has been developed, but the process technology and manufacturing cost are also very high.

Thanks to the fact that uncooled infrared thermal imagers can work at room temperature, the sensitivity and observation distance are relatively excellent, and they have particularly great advantages in terms of cost, power consumption, weight and life. In addition, the process technology is mature, so it can be applied to many types of conventional military fields, and the development prospects of the civilian market are also bright.

In recent years, infrared thermal imagers, as a key layout area of my country's emerging strategic industries, have shifted from the military field to the civilian field. The scale of the military market and the scale of the civilian market of infrared thermal imagers in my country are already on the same level. In the future, with the continuous accumulation and progress in the fields of electronic optics, data algorithms, image processing, etc., the application of uncooled infrared detector products will gradually tend to diversification and high-end development.

At present, it has been put into practical application in industrial production, food safety testing, security monitoring, preventive detection, fire protection, traffic monitoring, assisted driving, civilian night vision and other fields. In the future, with the further development of infrared thermal imaging technology, artificial intelligence and miniaturization design technology, the functions and application scope of infrared thermal imagers will be further expanded.
