本文讨论利用廉价的中波红外(MWIR)线列焦平面组件(FPA)首次成功进行的热成象的实验演示,该焦平面组件包含与焦平面上多路传输器(MUX)相互连的硒化铅(PbSe)长线列列阵。这种独特的缸外敏感器的设计由一个坚固的杜瓦瓶外壳构成,其中安装有一个可靠的固态热电致冷器(TEC),该热电致冷器与PbSe制备工艺和互补型金属-氧化物-半导体(CMOS)多路传输器这两项已被证实的技术相匹配。目前,把这些元部件组合起来,为那些系统性能需要较高分辨率和NE△T能力优于0.2℃的扫描型热成象应用,提供了一种采用容易获得的、廉价-高效的、第二代PbSe焦平面组件的系统设计。
This paper presents the first successful demonstration of thermal imaging using the inexpensive midwave infrared (MWIR) line focal plane assembly (FPA) that contains selenium, which is interconnected with the multiplexer (MUX) on the focal plane Lead (PbSe) long-line array. This unique off-cylinder sensor design consists of a rugged Dewar shell housing a reliable solid-state thermoelectric cooler (TEC) mounted with a PbSe process and a complementary metal-oxide Matter - semiconductor (CMOS) multiplexer has proven technology to match these two. At the present time, combining these components provides a scanning thermography application requiring higher resolution of the system performance and an NEΔT of better than 0.2 ° C, with an easy-to-use, inexpensive, highly efficient, System Design of Second Generation PbSe Focal Plane Components.
