Light scattering integrated intensity

These properties demonstrate that the study of photo-induced light scattering can be used to investigate the relaxor-kind phase transition by an optical method. Hereby, various measures can be used, like the temperature dependence of the intensity of the directly transmitted laser beam, of the integrated scattered light and of the intensity ratio R, respectively, as shown in Figure 9.9. 

In equation (4.51) of Chapter 4, the equal time structure factor, C (x), was defined. For light scattered from fluctuations in the dielectric properties of a material, it was shown that the light intensity was proportional to this quantity. In the problem of total intensity light scattering discussed in that chapter, the measurement is integrated over time and time-dependent fluctuations are not directly observed. When time-dependent fluctuations are...
