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.
