【摘要】 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。更多还原

【Abstract】 The state and trend of digital cooled infrared focal plane array detector assembly in USA,Israel and France were presented. According to the work mode of digital Read Out Integrated Circuit(ROIC),recent research results on digital cooled infrared focal plane array detector assembly in USA,Israel and France were introduced. By the concept of SWaP, some kinds of small pixel, HOT performance, digital output, million pixels mid-wave infrared focal plane array assembly were developed in Israel and France. At last the research result on digital cooled infrared focal plane array detector assembly in Kunming Institute of Physics was briefly introduced. The key technology of column-level ADC ROIC had been broken through, and the 640 ×512(15, 20, 25 μm pitch)column-level ADC digital cooled infrared focal plane array detector assemblies were developed. The performance measures of the digital detector in Kunming institute of physics were comparative with the digital detectors abroad.更多还原
