介绍了美国、以色列、法国等西方发达国家在数字化中波红外焦平面探测器方面的研究现状及发展趋势。从数字读出电路(ROIC)角度出发,阐述了上述三个发达国家开发的列级ADC数字化中波红外焦平面探测器的最新研究成果。在SWaP概念牵引下,以色列、法国都推出了小像元(中心距为10μm及以下)、高温工作、数字化输出的百万像素中波红外焦平面探测器组件。最后介绍了昆明物理研究所在数字化红外焦平面探测器组件研究方面取得的最新进展。昆明物理研究所突破列级ADC数字读出电路关键技术后,研制出一系列中心距(15μm、20μm、25μm)的640×512列级ADC数字化中波红外焦平面探测器组件,主要技术指标与国外同类数字化中波红外焦平面探测器组件相当。
The research status and development trend of digitalized infrared focal plane detectors in the western developed countries such as the United States, Israel and France are introduced. From the point of view of digital readout circuit (ROIC), the latest research results of the column ADC digitalized infrared focal plane detector developed by the above three developed countries are described. Driven by the SWaP concept, both Israel and France have introduced megapixel medium-wave infrared focal plane detector modules with small pixel (center distance of 10μm and below), high-temperature operation and digital output. Finally, the latest progress made by Kunming Institute of Physics in the research of digital infrared focal plane detector components is introduced. Kunming Institute of Physics broke through the column-level ADC digital readout circuit key technology, developed a series of center distance (15μm, 20μm, 25μm) 640 × 512 column ADC digital infrared infrared focal plane detector components, the main technical indicators and Similar foreign medium-wave infrared focal plane detector components quite.
