介绍了微扫描技术及其给红外焦平面阵列(FPA)成像带来的好处,分析了微扫描红外焦平面阵列成像方案的特点,比较了各种微扫描成像方案的优势及不足,指出了红外焦平面阵列微扫描成像工程化的可行方案和研究方向。设计了一种采用非制冷氧化钒384 pixel×288 pixel焦平面探测器的长波红外微扫描光学系统。其工作波长范围为8～14 μm，F数为1，焦距为150 mm。利用光学设计软件Code Ⅴ进行了仿真计算，对其像质进行了评价，并给出了微扫描系统的配置方案。

Micro-scanning technique and its benefits in infrared focal plane array (FPA) imaging are discussed. Different micro-scanning schemes and their property are described in detail. The advantages and drawbacks of each scheme are compared. The possible schemes for engineering application are presented. The research direction in micro-scanning infrared focal plane array imaging is pointed out. As an example, we design a micro-scanning optical system suitable for long wave infrared optical system whose operating wavelength range is 8～14 μm, F number is 1, and focal length is 150 mm. It was an uncooled 384 pixel×288 pixel VOx focal plane array detector. Moreover, its image quality is evaluated with the Code Ⅴ optical design software. And the infrared mico-scanning system configuration is also introduced.
