    傅立叶变换红外(FTIR)光谱仪是根据光的相干性原理设计的,因此是一种干涉型光谱仪,它主要由光源(硅碳棒,高压汞灯),干涉仪,检测器,计算机和记录系统组成,大多数傅立叶变换红外光谱仪使用了迈克尔逊(Michelson)干涉仪,因此实验测量的原始光谱图是光源的干涉图,然后通过计算机对干涉图进行快速傅立叶变换计算,从而得到以波长或波数为函数的光谱图,因此,谱图称为傅立叶变换红外光谱,仪器称为傅立叶变换红外光谱仪

Infrared spectroscopy is an effective method to identify substance and analyze the structures of molecular. Fourier transform infrared (FTIR) spectrometers developed in the seventies are a typical representative of the third generation of infrared spectroscopy. They are a kind of interference-type spectrometers which were designed based on the principle of coherent light, with excellent features and perfect functions. And they haven’t only been used widely but also have extensive prospects. In this paper, the basic principles of Fourier transform infrared spectrometer are described briefly. The main features of FT-IR were summed up as well as its application in various fields, and some basic opinions of developmental direction as far as FTIR were put forward.

Key words: Fourier transform infrared spectrometer; Basic principles; Application; Development

傅立叶变换红外光谱仪在临床疾病检测方面也有广泛的应用, 如利用红外光谱法对冠心病、动脉硬化、糖尿病、癌症的检测。红外光谱法测定蛋白质基体中的葡萄糖含量。以及用FT-Raman 光谱在700~1900cm- 1处的差异, 对胃、牙齿、血管、肝等人体组织的研究可用于体内诊断。
