5DX傅里叶变换红外光谱仪(FTIR)中的激光系统,是整个仪器的关键部件之一。在FTIR光谱仪中,用迈克尔逊干涉仪实现调频分光。干涉仪的中心部分是动镜及其伺服控制系统。使用He—Ne激光器的激光干涉系统和主干涉仪配合,以其发出的波长为6328A的单色光,监控动镜移动的速度和距离;同时又利用这束光经过干涉后得到的不变余弦干涉图数据采样的标度。其他仪器,如170SX内另有一套激光系统,作为仪器检修和调整时的水平调整激光源。
The laser system in the 5DX Fourier Transform Infrared Spectrometer (FTIR) is one of the key components of the overall instrument. In the FTIR spectrometer, Michelson interferometer to achieve FM spectroscopy. The central part of the interferometer is the moving mirror and its servo control system. The laser interferometer system using the He-Ne laser cooperates with the main interferometer to monitor the moving speed and distance of the moving mirror with the monochromatic light whose wavelength is 6328A. At the same time, the invariant cosine Interferogram Data Sampling Scale. Other instruments, such as 170SX laser system within another set, as the instrument maintenance and adjustment of the level of adjustment laser source.
