Optimized Calibration of Terahertz Polarimetric Imaging Systems With Imperfect Polarizers for Accurate Jones-Matrix Mapping
This paper presents an optimized in situ calibration framework for terahertz polarimetric imaging systems that models imperfect wire-grid polarizers and determines optimal rotation angles to accurately recover sample Jones matrices using a minimal set of measurements, thereby reducing systematic errors and enabling faster, reliable field-deployable imaging.
