Summary

Researchers designed a polarization-sensitive holographic imaging system capable of identifying transparent microplastics through scattering media by measuring the degree of linear polarization (DoLP) as an angle-independent discriminating feature. The system enables non-destructive differentiation of microplastic types in turbid or complex optical environments where conventional imaging methods fail.

A polarization-sensitive holographic imaging system is designed for identifying transparent microplastics (MPs) through scattering media. The degree of linear polarization (DoLP) is an angle-independent feature for distinguishing different types of MPs.
