红外显微成像技术诞生于20世纪90年代中期， 该方法的应用研究在国外刚刚起步， 而在国内这项技术还未被广泛认识。 它是一种快速、 无损的检测技术， 具有图谱合一、 微区化、 可视化、 高精度和高灵敏度等优点。 文章概述了红外显微成像系统的组成、 工作原理及工作方式， 重点介绍了其在生物医学、 微生物学、 法庭科学、 材料学、 营养饲料学以及农产品质量检测方面的研究进展， 分析了红外显微成像技术的研究难点， 并对其发展趋势进行了展望。

FTIR microspectroscopy technique was born in the mid-nineties. The research on this technique has just began abroad, and this technology has not yet been widely recognized in China. It is a rapid, nondestructive testing technology, has the advantages of microdomain, visualization, high precision and high sensitivity. In the present study, the composition, operational principle and working mode of FTIR microspectroscopy were summarized. The progress in application of FTIR microspectroscopy technique was investigated in some fields, including biomedicine, microbiology, forensic science, materials science, nutrition and feed science and agricultural products. The difficulty of FTIR microspectroscopy research and the prospects of this technique were also discussed.
