The basic theory and design method of a broad-band spatial heterodyne interferometric spectrometer was researched based on the multi-order diffraction of echelle grating. The characteristics of the heterodyne interferometric spectrometer was described and the relationships between the instrument performance parameters (such as spectral resolution
spectral range
signal-to-noise ratio
field of view
and diffraction order) and the initial optical and electronic parameters (such as echelle grating
field prism
imaging system and detector) were discussed. Then
an experimental platform for the broad-band spatial heterodyne spectrometer was settled to demonstrate the above discussions. The designed spectral resolution is 0.173 cm

a sodium lamb (589 nm
589.6 nm) and a mercury lamb (576.96 nm、579.07 nm). It shows that the average wavenumber sampling interval of recovered spectra is 0.17 cm
