Abstract
Double slits have been incorporated in a flat field spectrometer to record spatially resolved and integrated spectra simultaneously. Variation of the absorbed irradiance and ionisation stage along the fibre plasmas has been monitored. By comparison of the spatially resolved and integrated resonance line ratios, it is found that the spatially integrated values deviated significantly from the real experimental circumstances due to nonuniformity along the plasmas.
