In 2020, because of covid-19, normal social order will be disrupted, and the real economy will suffer a huge impact; the Sino-US trade conflict will intensify, the international situation will become more severe, and the global industrial chain will face unprecedented challenges. However, Chinese infrared thermal imaging detector manufacturers have risen to difficulties, innovated independently, and found opportunities from the crisis to achieve leapfrog development and reshape the new pattern of the global infrared industry: Chinese infrared thermal imaging detector manufacturers are already able to compete with foreign manufacturers "The Chamber Rebelled."

In terms of epidemic prevention and temperature measurement products, Chinese infrared thermal imaging detector manufacturers have increased their investment in the supply chain, production, research and development, and rapidly improved their delivery capabilities. The products are widely used in airports, railway stations, hospitals, subway stations, and schools throughout the country. Such as crowded public places, to achieve "non-contact temperature measurement", "large-scale population real-time temperature measurement", "automatically capture fever population" and other functions, to achieve accurate identification, ensure that targets are not missed, and assist the government in epidemic prevention The first line of defense for control has been widely recognized by the market. Therefore, the operating income and profits of "China brand" temperature measurement products and infrared thermal imaging detectors have increased significantly, and shipments far exceed the same period last year.

In addition, the infrared thermopile detectors in various handheld anti-epidemic temperature measuring instruments (such as forehead thermometers and ear thermometers) were in short supply and became the "popular" chip in 2020. At present, Chinese manufacturers are actively deploying thermopile array technology. , Expecting to expand a broader application space: smart home represented by air conditioning, lighting, and security, smart retail represented by passenger flow statistics and behavior analysis...

The rapid rise of China's infrared thermal imaging industry chain and the rapid decline in the cost of core detectors have brought new development opportunities. In the era of the Internet of Everything, infrared thermal imaging will become an indispensable part of "multi-dimensional perception" with its important performances of "night vision" and "non-contact temperature measurement", and its application fields are becoming wider and wider: from cars to mobile phones, From drones to robots, from smart homes to wearable devices. Looking back on the spring of 2021, new products such as infrared movement, infrared thermal imaging camera, and "infrared + artificial intelligence (AI)" perception solutions are emerging in endlessly.

Is the infrared temperature measurement value reliable? Will there be a large error? In daily life, we will find that the accuracy of infrared thermometers is easily affected by the external environment, and the measurement results and actual body temperature may sometimes be quite different. Therefore, in order to obtain accurate measurement data, the most important thing is to improve the quality standard of infrared products. In order to make the infrared temperature measuring instrument have a higher output signal-to-noise ratio, a larger optical relative aperture, a high-sensitivity infrared detector and a low-noise signal processing circuit are required. In order to make infrared temperature measuring instruments have higher measurement accuracy, measures such as emissivity correction, ambient temperature compensation and correct temperature calibration (calibration) must be taken.
