自从1947年双光束类型的红外光谱仪问世以后,红外光谱法很快就在化学领域里得到广泛的应用,对有机化学的发展作出了重要的贡献。现在,红外光谱已是公认的重要分析工具之一了。但是,随着近代科学技术的迅速发展,这种以色散元件(如光栅、棱镜等)为主要分光系统的光谱仪器在许多方面就不能完全满足需要了。例如,仪器的工作波长范围伸向远红外区不够远,光谱仪在测定样品时的扫描速度不够快,对吸收红外辐射很强的样品或者是信号很弱的样品的测定以及痕量组分的分析、瞬间状态的研究等,都有一定困难,妨碍了红外光谱的进一步应用。这就要求能有一种新型的高操作性能的光谱
Since the advent of the dual-beam infrared spectrometer in 1947, infrared spectroscopy has rapidly gained widespread use in the chemical field, making an important contribution to the development of organic chemistry. Infrared spectroscopy is now recognized as one of the most important analytical tools. However, with the rapid development of science and technology in modern times, this kind of spectrometer, which uses the dispersive components (such as grating and prism) as the main spectroscopic system, can not fully meet the needs in many aspects. For example, the operating wavelength range of the instrument is not far enough to reach the far-infrared region. The spectrometer does not perform fast enough to measure the sample. It can not detect the sample with strong infrared radiation or the signal with weak signal and the trace component , The transient state of research, have certain difficulties, hinder the further application of infrared spectroscopy. This requires a new type of high performance spectroscopy
