介绍了一种将可见光图像转换为红外图像的装置.装置的核心器件是利用MEMS工艺制作的可见光/红外图像转换芯片.红外图像生成装置包括可见光图像生成系统、可见光/红外图像转换系统以及红外图像投影光学系统三部分.红外图像生成装置产生的红外图像辐射波段覆盖8~12μm,分辨率达到了20 lp/mm,可模拟温度范围为20~150℃,图像非均匀性小于5%,几何畸变小于3%.

This paper presents a visual to infrared transducer based on an infrared image converter chip fabricated by micro electro mechanical systems （MEMS）. The infrared image projector consists of three parts, which are visible light image generation system, infrared image converter and the infrared image projection system. This infrared image transducer covers the radiation band of 8-12 μm. Its reso- lution is 20 lp/mm and the apparent temperature range is 20 ℃ to 150 ℃. Non-uniformity of the image generated by infrared image projection device is less than 5% and its geometric distortion is less than 3%.
