摘要
非制冷红外焦平面技术在过去的几年内飞速发展,非制冷焦平面由原来的小规模,发展到中、大规模320×240和640×480阵列,在未来的几年内有望获得超大规模的1024×1024非制冷焦平面阵列.像素尺寸也由50 μm减小到25 μm,提高了焦平面的灵敏度,使非制冷红外热成像系统在**领域得到了成功应用,部分型号已经装备于部队,并受到好评.今后,随着焦平面阵列规模的不断增大、像素尺寸的进一步减小,非制冷热成像系统在**领域的应用将越来越广泛,尤其在轻**瞄具、驾驶员视力增强器、手持式便携热像仪等轻**方面,非制冷热成像系统在近年内有望逐步取代价格高、可靠性差、体积大等笨重的制冷型热成像系统.
Abstract
From small scale to medium and large scale 320×240, 640×480 uncooled focal plane array (UFPA), uncooled infrared technology has been developed rapidly in recent years, and 1024×1024 FPAs are expected in the future. The pixel pitch is also developed from 50~25 μm, and the sensitivity is improved largely, so that the thermal imaging system is applied successfully in military affairs. Part model has been armed in military and measured well. In the future, with the developing larger scale and smaller pixel of UFPA, the application of uncooled thermal imaging system will be wider, especially in light thermal weapon,such as light weapon vision, driver vision enhancer and handle thermal system, uncooled thermal imaging system is expected to replace the high price, low reliability, big bulk cooled thermal imaging system gradually in recent years.
