| Abstract: | Spatial Heterodyne Spectroscopy (SHS) is a new spectroscopic technique which can obtain high spectral resolution. It combines the advantages of grating and Fourier-transform Spectroscopy (FTS) techniques. The basic concepts and structure of spatial heterodyne spectrometer were described. Spectrometer operating on the SHS principle was presented. SHS system were built and tested in the laboratory, the basic concepts and performance characteristics of the technique were verified. Experimental results showed that the achieved resolving power of SHS system is 17700 at 591nm, and the spectral range is 17nm. Spectral experiments were operated on the SHS system, including laser, continuous sourse, Hg lamp and Na lamp. These experimental results demonstrate the capability of spatial heterodyne spectroscopy in detection of high resolution spectrum. |
