Light scattering for measurement

Equation (6.29) is the governing equation for the use of homodyne, dynamic light scattering for measurement of velocity gradients. What is left is to specify the shape of the intensity distribution of the incident light within the scattering volume. As an example, if... 

Beyond this physical method using photography or light scattering for measuring a, the chemical method based on sulfite oxidation is often successfully used despite disadvantages due to different fluid properties. According to the theory of mass transfer with simultaneous chemical reaction, A can be calculated from... 

The amplitude of the scattered field Eg varies with time due to the fluctuations in the director orientation and hence the dielectric tensor. Therefore, a very convenient way to observe the director dynamics is to study the dynamics of the scattered light, i.e. to use dynamic light scattering for measuring the autocorrelation function of the scattered light. The normalised intensity autocorrelation function (q, tf) is defined as [11]...
