Detailed study on the role of forward scattering in particle sizing based on spherical particle model

摘要

It is detailed studied that whether the forward scattering is suitable for particle sizing by both of the theory analysis and numeric simulation based on spherical particle model. The detailed theory analysis indicates that usually the kernel matrix in the forward region is more ill-conditioned than that in other regions. The numerical simulation also indicates that under the same conditions, the particle sizing results from the forward region are generally much worse than those from other scattering regions. Therefore, we think that in the future particle sizing related studies the forward scattering should be avoided.
