The scattering intensity is generally not strongly dependent on the wavelength, but is sensitive to the particle size.
It eliminates fiber tilt, unwarps the detector image, and corrects the scattering intensity.
The important experimental point to remember is that dust will also scatter light and contribute to the scattering intensity.
If is not too large, one need only measure the scattering intensity at 90 and two angles symmetrical about 90 , usually 45 and 135 .
In other cases, the scattering intensity is enhanced in backward direction.
One or many detectors are used to measure the scattering intensity at one or many angles.
From the scattering intensity, one can deduce the size of each aggregate, and construct a detailed aggregate size distribution.
These complications are often more than offset by the fact that the dynamic enhancement of the scattering intensity is significant.
In this case, the scattering intensity is proportional to the fourth power of the reciprocal wavelength of the incident photon.
If the light source is a laser, and thus is monochromatic and coherent, then one observes a time-dependent fluctuation in the scattering intensity.
