GLOBAL-OPTIMIZATION APPROACH OF SPECTRUM RECONSTRUCTION

Andrzej Miękina, Roman Z. Morawski
  • Abstract:
    The paper is on the usefulness of global optimization for developing variational algorithms of spectrophotometer calibration. A new nonlinear method for reconstruction of absorption spectrum, on the basis of spectrophotometric data, is proposed and used for demonstrating that the quality of reconstruction depends on the ability of the calibration procedure to reach a global minimum during optimization of the parameters of the operator of reconstruction. The results obtained using calibration algorithms based on local and global optimization are compared in terms of measurement uncertainty and artefact content.
