The Dynamic Light Scattering of Collimated Gaussian Beam under Simple Harmonic Binding by Brownain Particle in Colloid

The statistic characteristics of Brownain particle in colloid solution are investigated and the autocorrelation function of the scattered light electric field of the dynamic light scattering is solved only when we regard the interaction of the scattered particle as a simple harmonic force, the incident light as a collimated Gaussian beam and the scattered light as an ideal plane wave.The different points between the conclusion of the new model and the conclusion of the original model are discussed and they have been simplified as the approximate conditions of the same conclusions. With the obtained results have been applied to the occasion where the external electric field exists,the corresponding autocorrelation function of the scattered light electric field is botained.The described method and conclusion can be directly applied to the experiments and research work,and can be popularized to the quantitative analysis of multiple disperse systems.
