Solution of the inverse problem of light
beating spectroscopy using singular value decomposition (SVD) method for the
analysis of polydisperse suspensions of nanoparticles
Abstract
The results of numerical solution of the
inverse problem of light beating spectroscopy using using singular value
decomposition (SVD) method are presented. The developed algorithm takes into
acount the positivity of the solution and the constant background signal.
Reconstructed uni and multimodal distributions are presented. The effect of the
noise of the input signal, the background signal and the frequency bandwidth
of the measured signal on the characteristics of the reconstructed
distributions is discussed.
Key words: singular value decomposition,
SVD, light beating spectroscopy, nanoparticles, solution, size distribution.
