Abstract :
A modified Spatial Heterodyne Spectrometer (SHS) is used for measuring atomic emission spectra for instance in LIBS experiments. This device is basically a Fourier Transform Spectrometer, but the Fourier transform is taken in the directions perpendicular to the optical propagation and heterodyned around one specific wavelength. Therefore, this device uses no movable parts. The resolution of the device is sufficient to distinguish common isotopic lines.
