There are many factors affecting the resolution of laser particle size analyzer
(1) The more photodetectors there are, the higher the resolution;
(2) Inverse algorithm: good inverse algorithm leads to high resolution;
(3) Distribution models: high resolution of multi-peak model and low resolution of single-peak model;
(4) Fourier lens: Fourier lens with low phase contrast leads to high resolution while the Fourier lens with high phase contrast leads to low resolution.
