Spectroscopy self-beat

In the detection of the autocorrelation functions in self-beat spectroscopy, solution polydispersity can lead to a non-exponential form. If we assume that there are no contributions to the autocorrelation function except those from translational diffusion for the different types of molecules, we can consider two simple cases a continuous distribution of solute particle sizes and several distinct components in a solution. We shall approach the two cases by determining their effect on the observed correlation function. 

From the description presented here, it can be seen that self-beating spectroscopy as a technique for measuring the diffusion coefficient of... 

We will illustrate homodyne spectroscopy (self-beating spectroscopy) with some examples. 

The field is thus sometimes called light beating qtectroscopy or intensity fluctuatiou spectroscopy, li also goes by the iiaiite of dynamic liglit scallcriug. In the absence of a reference beam it is called "self-beating" spectroscopy and...
