摘　　要：傅立叶变换红外显微光谱技术具有测量灵敏度高、微区分析和无损检测等优点,在材料学、医学、生物学等领域得到广泛的应用。由于常规红外光源的低亮度、低空间分辨率、得到的显微光谱信噪比差,限制了红外显微光谱技术的应用。同步红外辐射以其高亮度的特性成为傅立叶变换红外显微光谱技术的理想光源,将其分辨率提高到接近红外波长或衍射限,极大地提高了红外显微光谱的质量。F-FIR microspectroscopy has many advantages, such as high sensitivity, tiny area analysis etc. It has wide applications in material science, medicine, biology, and so on. Because of the low brightness of traditional infrared light source, the spatial resolutio and the signal-to-noise （S/N） will do lower. It has restricted the application of FTIR microspectroscopy. Synchrotron infrared radiation has become the ideal light source to FTIR microspectroscopy because of its high brightness. The spatial resolution is incresased close to infrared wavelength and diffraction limit. The quality of the infrared micropectroscopy has an evident improvement.
