Abstract
It is shown in this paper that in geometrical space two polarization planes of the linearly polarized light waves scattered by particles in measuring ellipsoid constitute an angle of π/2. while in sequence of time the signals sent out by two symmetric pholodetectors in PLDA are separated by a phase angle π. This property of PLDA enables the improvement of SNR.
The similarity between power spectrum of photoelectrical current of PLDA and probability density function p d(u c) of investigated flow velocity has been proved theoretically and checked by agreement of obtained results with classical theory and generally accepted experiments.
