Investigation of Scattering Intensity Dependencies on the Optical System Parameters in Cross-Correlation Spectrometer

The cross-correlation method is an optical method used for studying particle sizes in liquid dispersed samples. In this work, we describe our estimations of the intensity of laser radiation scattering in a cross-correlation spectrometer depending on a number of parameters of the optical system, such as the focal length of the lens system, beam divergence, and the angle between incident beams. With help of presented calculations, one can increase the power of detected scattered signal and signal-to-noise ratio in cross-correlation spectrometers scheme.
