analysis," Appl. Opt. 29, 4159-4169 (1990)
We describe the design, construction, and testing of a miniature, all-solid state
laser light scattering instrument for determination of particle sizes and
distributions using photon correlation spectroscopy techniques (i.e.,
quasielastic or dynamic light scattering). Detailed comparative tests with
standard photon correlation spectroscopy equipment are presented.

In sucrose, affecting apparent size. Absolute diameters are of less
importance here than direct comparison of size measured from the same
samples by the two PCS systems.
The two points (—) represent such poor correlograms after 3 min
of integration as to be most unreliable.
