of >75 m on MDPE water pipes, to within 1 m accuracy and with a processing time of under 2 minutes.
As described by these equations, light scattering is pronounced when the correlation distance is in the range of the wavelength of visible light.
the correlation distance, would be larger than the wavelength of visible light.
Moreover, from the viewpoints of the correlation distance, the spatial size of the fluctuation in the polarizability difference is considerably smaller than the wavelength of visible light, which would also be responsible for improving transparency.
where K is approximately constant for a given diffraction profile and A(L) and B(L) denote the cosine and sine Fourier coefficients, respectively, belonging to correlation distance L.
Second, the expressions for the line profiles are only reliable for relatively small correlation distance.
A good fit is obtained up to a correlation distance of about 15 nm.
Extrapolating the first few data of the size coefficients with a straight line to the correlation distance axis yields the so-called apparent grain size .
Figure 4 represents the Debye-Bueche plot for the PVC/DHP system, where the short-range correlation distance [a.
The value of the long-range correlation distance [a.
In addition, the short-range correlation distance [a.
Both the short-range and long-range correlation distances of three plastisols are calculated and presented as a function of temperature in Figs.
