【Abstract】 Based on a mercury cadmium telluride material system, advanced infrared detector technology has entered the fast track of systematic development. After nearly 60 years of development, the mercury cadmium telluride infrared detector has become the baseline for high-performance infrared detectors. Three generations of iterations have been completed, and the fourth generation is being explored. In recent decades, indium antimonide, quantum wells, type II superlattices, quantum dots, and other material systems have comprehensively competed with the mercury cadmium telluride system. To date, no material system has fully achieved the performance of mercury cadmium telluride material system. The Kunming Institute of Physics(KIP) independently completed the development and production of the first-generation infrared detectors, the mass production of the second-generation infrared detectors, and the engineering of the third-generation infrared detectors. The array of medium and short wave FPAs is 2048×2048, the array of dual-band FPA is 640×512, and the cut-off wavelength is more than 15 μm. The NETD reaches 3 m K, and the working temperature of the medium wave FPA reaches 150 K, which is close to the international advanced level. Recently, the KIP took the lead in proposing the specific connotation for the new generation of infrared detection technology, which takes the photon count level limit sensitivity and multi-dimensional information of all light perception as the main characteristics, going beyond the scale, pixel,and photovoltaic technology as the main approach, and seeing clearly and cleverly as the main goal, promoting the upgrade of the infrared photoelectric detection application.更多还原
