Separation of the Overlapping Spectral Lines Using Derivative Spectra

A code package is written to determine the maximum positions and half-widths of overlapping spectral lines forming the total profile. This package allows us to reconstruct spectral line profiles forming the total shape based on the experimental spectrum. An analysis is carried out based on the n-th derivatives of the line shape under study

Radial Characteristics of Radiation of High-Frequency Electrodeless Lamps

The radial dependences of the radiative characteristics of high-frequency electrodeless lamps (HFELs) using as a working medium either a mixture of mercury and argon or helium have been investigated in experiments and numerical simulations. The intensities of the mercury line at a wavelength of 546.1 nm and the helium line at 587.6 nm have been measured

Calculation of the Real Spectral Line Shape by Solving the Ill-Posed Inverse Problem

The solving of the ill- posed inverse problem for spectral line shapes or problem of reduction to the ideal spectral device is discussed in this paper. Two different methods were used to determine the real spectral line profile and to separate the instrument function: i) solving the ill-posed inverse problem by means of the Tikhonov’s regularization method; and ii) the mathematical modelling by means of a non-linear multiparameter chi-square fit. The solution of the inverse problem by the Tikhonov’s regularization method was implemented using program written in Delphi. The results of the test and statistical modelling of this program were presented. The mathematical modelling for the estimation the true profile and fitting the modelled line to an experimental profile by a non-linear multi-parameter chi-square procedure was used for the validation and comparison
