Abstract

We performed this work to estimate the errors of the device for measurement of light scattering matrices (LSM). The scheme of a laser polarizational nephelometer with polarization modulation by the phase plates rotating with a speed ratio of one to five was taken for analysis. For this scheme the influence of the adjustment errors on the LSM elements of different test objects was evaluated by the Monte-Carlo method, and we have found the matrix of empty space to be the most sensitive to the errors. Dependencies of the matrix error upon the different adjustment parameters have been plotted for the matrix of empty space. Also we have studied dependency of the errors from the intensity of scattered light and the distortions in the registration unit. We also analyzed the modulation of the polarization state by rotation of the phase plates. We studied the condition number [cond(C)] of the matrix of conversion of the input signal Fourier spectrum to LSM was under investigation. Dependencies of cond(C) versus the initial orientation of the phase plates axis and the phase shift values were investigated.
