摘　　要：为了实现高分辨率、宽波段的空间外差拉曼光谱探测,使用中阶梯光栅的四个衍射级次,每个级次的对应一定范围光谱,总的光谱探测范围得到了扩增,最终根据设计,搭建了一台中阶梯光栅-平面镜的空间外差拉曼光谱(Echelle-Mirror Spatial Heterodyne Raman Spectroscopy,EMSHRS)实验平台。通过标准光源进行光谱定标得到该仪器的理论光谱分辨率为1.033 cm^(-1),单个衍射级次对应的波段宽度为1058 cm^(-1),最后对三种无机物进行了光谱探测和分析,实验结果表明中阶梯光栅-平面镜型空间外差拉曼光谱技术可实现对无机物的快速、高分辨和宽波段检测,具有良好的应用前景。In thispaper,an Echelle-Mirror Spatial Heterodyne Raman Spectrometer(Echelle-Mirror Spatial Heterodyne Raman Spectroscopy,EMSHRS)breadboard was designed and built using four diffraction order of an echelle.The calibration procedure is performed using a standard lamp to estimate the spectral resolution(1.033 cm^(-1))and spectral range of one diffraction order(1058 cm^(-1)).The Raman spectrum of p n-pentane,n-octane and isopropyl alcohol are discussed,which demonstrate that the EMSHRS has great prospects for fast and broadband detection in inorganic compounds.
