Microplastics (MPs), first identified in 1972 and defined by U.S. National Oceanic and Atmospheric Administration (NOAA) as particles smaller than 5 mm, are either primary or secondary based on their origin . Plastics like polyethylene (PE), polypropylene (PP), and PET dominate packaging due to their strength and light weight. However, extensive plastic use in packaging leads to significant environmental and ocean pollution. Detection of microplastics (MPs) is crucial for healthcare and food quality inspection. Non-contact methods like polarization imaging (PI) and digital holography (DH) capture MPs’ physical features, but have limitations individually. Combining DH’s real-time amplitude and phase data with PI’s leads to polarization information enhancement for comprehensive and effective MP analysis.Here in this work, we introduce the polarization in the DH microscope called the polarization Digital Holography microscope (PDHM) for detecting MPs
