摘要
文章介绍了红外光谱图像技术；介绍了用焦平面阵列检测器、步进扫描傅里叶变换光谱仪、红外显微镜、分束器构成的红外光谱图像硬件系统及信息提取的软件方法；给出了用红外光谱图像分析猴脑组织中蛋白质和磷脂差异、残留在人胸部组织中的硅酮、水稻叶片等３ 个在生物学研究中的应用实例；指出了红外光谱图像技术进一步的发展方向是采用同步辐射作为光源。
Infrared spectroscopic imaging is reviewed.The hardware system,consisting of a focal plane array detector,step-scan Fourier transform infrared spectrometer,infrared microscope,and image formation lens,and the information extraction software are described.Examples of applications in biology are given.Future developments of this technique include adopting synchrotron radiation as the optical source,employing mathematic methods to increase resolution,and developing spatial chemometrics to obtain spatial information.
