Polarimetric analysis of whitefly larvae on pomegranate leaves via Mueller matrix imaging

This study explores the use of Mueller matrix imaging polarimetry (MMIP) to analyze whitefly larvae on a pomegranate leaf. Utilizing a dual-rotating retarder setup, we captured detailed Mueller matrix images of the infested leaf with whitefly larvae and after removing them. Through polar decomposition, we quantified depolarization, diattenuation, and retardance properties, providing insights into the structural and optical characteristics of the sample. The results indicate that the presence of larvae significantly alters the depolarization and retardance parameters, demonstrating the efficacy of MMIP in discerning fine structural and compositional changes in plant tissues.
