Spatially-encoded fourier spectrometer: Prospects for plasma studies

Analysis of the main characteristics (geometrie factor, resolving power, signal-to-noise ratio) of a spatially-encoded Fourier spectrometer (SFS) with recording by a position-sensitive photodetector shows that it can be widely used for piasma studies. A sum of advantages of the SFS appears to be the...

Summary:Analysis of the main characteristics (geometrie factor, resolving power, signal-to-noise ratio) of a spatially-encoded Fourier spectrometer (SFS) with recording by a position-sensitive photodetector shows that it can be widely used for piasma studies. A sum of advantages of the SFS appears to be the best in comparison both with grating (prism) spectrographs and a classic "dynamie" Fourier spectrometer. A technique, suggested for numerical correction of imperfection of optical elements of the SFS, enables to reach a resolution close to the theoretical one. Examples of measurements of different spectra are given.
