Recently, after overcoming a number of technical difficulties, 11 technical teams of China Electronics Division successfully developed short-wave and medium-wave single-chip 2.7K×2.7K infrared focal plane detectors, and carried out imaging demonstrations with good results. The successful development of the detector marks a major breakthrough in the development of three generations of super-large array infrared detectors by China Electronics, filling the domestic single-chip 2K×2K array scale infrared detector blank, representing the highest in the country and the world advanced. Level. 
The picture shows an infrared image detected with a 2.7K x 2.7K infrared focal plane detector.
Infrared detection detects the thermal radiation of the target object itself, converts the difference between the temperature and the emissivity of the object into a video image signal, and obtains infrared imaging of the target object. It is a passive detection, which has good concealment, anti-interference, easy identification, camouflage, and rich information. Advantages, widely used in early warning detection, search and tracking, astronomical observation, remote sensing, maritime rescue, medicine and other fields.
Infrared focal plane detector is the core component of infrared imaging system. This short-wave and medium-wave single-chip 2.7K×2.7K detector is a high-sensitivity cooling infrared focal plane detector, involving materials, chips and integrated circuit design. Various disciplines such as refrigeration and packaging are extremely difficult. Previously, single-chip 2K×2K array-scale infrared focal plane detectors were only mastered by individual countries.
The successful development of China's electric short-wave and medium-wave single-chip 2.7K×2.7K infrared focal plane detectors has made China the second country to master this technology after the United States, which not only achieved zero breakthrough in domestic products. , but also laid the company's leading position in the three generations of large area array infrared detector components developed areas.
