Market application of uncooled infrared focal plane detectors

The uncooled infrared thermal imaging market has currently reached a scale of nearly 8 billion U.S. dollars. With the progress of localization of uncooled infrared focal planes, my country's infrared thermal imaging market has developed rapidly, and even reached 40% of the global market during the 2020 epidemic. above. The technical applications of uncooled infrared thermal imaging products can be summarized into three main directions: visual enhancement, non-contact temperature measurement, and preventive detection.

Vision enhancement applications are mainly based on infrared thermal imaging that does not require external light sources. It has the advantages of high contrast between thermal targets and the surrounding environment, good ability to penetrate smoke, and all-weather operation day and night. It is widely used in military defense, security, automotive assisted driving, and outdoor hunting. and other fields. In the military field, it is used in infrared terminal guidance, weapon sights, individual soldier equipment, UAV pods, etc. In the security field, it is used in perimeter protection, key area monitoring, fire alarm, fire search and rescue, etc. Infrared assisted driving has the characteristics of long detection range and is not affected by smoke, sunlight, and glare, which can increase the safety of driving at night. In outdoor hunting and outdoor sports such as mountain climbing, camping, and exploring, infrared thermal imaging can be used in completely dark environments and can overcome rain, fog, plants and other obstacles to produce clear images, helping to find prey and identify dangers.

Preventive detection applications mainly use infrared thermal imaging cameras to detect abnormal heating of equipment to prevent major shutdowns and production accidents. The power industry uses thermal imaging cameras to inspect and diagnose the status of power equipment such as transformers, capacitors, circuit breakers, insulator strings, transformers, generators, etc., to improve the operational reliability of power supply equipment and reduce equipment maintenance time. It is the most mature and effective method. Online power detection method. Various manufacturers are studying uncooled infrared focal plane detector technology to improve equipment accuracy, using high-definition thermal imaging modules to obtain more detailed information on equipment temperature, and comprehensively monitor the operating temperature status of substation equipment and micro equipment. This technology comprehensively improves the temperature measurement algorithm, automatically adjusts the internal working parameters of the detector according to the operating temperature status of the monitoring equipment, improves temperature measurement accuracy, and completes early analysis and judgment of abnormal working status of substation equipment. At the same time, high-resolution surface temperature data is integrated into the AI intelligent analysis platform to fully reflect the working status of substation equipment with the help of AI technology. Infrared imaging technology can detect building defects that are invisible to the naked eye such as poor insulation, water seepage, pipe transportation, mold, etc. through the temperature distribution on the building surface. Non-contact measurement of tank levels in the petrochemical industry distinguishes small temperature changes between liquids or solids of different densities with specific heat properties. In mines, the process of extracting minerals from ore can be monitored and assist in the operation and maintenance of electromechanical systems.

Thermal imaging non-contact temperature measurement is a technology that provides image-based automatic temperature detection and analysis for automated process control applications. It has been widely used in electronic assembly defect detection, automobile manufacturing, metal smelting, food monitoring, textile processing and other fields. . The demand for non-contact body temperature detection infrared thermal imaging cameras has increased significantly during the epidemic, and it is mainly used for rapid screening of abnormal body fever in public places such as airports and train stations. In the field of medical diagnosis, infrared thermal imaging is used for the diagnosis of painful diseases such as shoulder and neck pain, cervical and lumbar spondylosis, and myofascial pain. It is also an important means of visualizing traditional Chinese medicine diagnosis and treatment. Various manufacturers are actively researching intelligent infrared imaging temperature measurement technology to achieve accurate correction and measurement of equipment surface temperature, improve measurement accuracy at different distances, angles and ambient temperatures. At the same time, the obtained three-dimensional temperature distribution field on the equipment surface is used to achieve internal temperature measurement of typical equipment. Field inversion detection enables visual diagnosis and analysis of the internal heating conditions of the equipment, enabling the application of a new generation of infrared diagnostic equipment.
