Abstract

A new dynamic light scattering analysis method based on modern power spectral estimation was proposed to resolve problems on lower resolution and variance

and power spectrum leakage in the current dynamic light scattering software.The modern power spectrum estimation algorithm and measurement system were studied. Firstly

the photon correlation spectroscopic theory and the scattering spectrum estimation of dynamic light scattering measurement were introduced. Then

the dynamic scattering spectrum based on modern power spectrum estimation was descripted in detail

and the order of

was calculated particularly. Furthermore

the measurement system was described

in which the hardware components included optical systems and signal processing system and the software showed the development process. Finally

a experiment was carried out on the latex particle sample solution with the particle diameters of 30

100 nm and solution transmission of 96%. The results show that the average values of the measurement error and repeatability error are 1.88% and 1.62%

respectively

which can achieve the national standard that the measurement and repeatability errors should be less than 2%

respectively.
