Abstract

Mueller matrix polarimetry allows for sophisticated analysis of polarization-sensitive information and enhanced contrast in imaging but is particularly cumbersome and slow in the case of terahertz (THz) frequency measurements. We have recently debuted our THz Portable HAndheld Spectral Reflection (PHASR) Scanner as a versatile tool for high-speed broadband time-domain spectroscopic imaging of 1 inch scenery in about 6-8 seconds. We present the design of the polarization-sensitive THz PHASR Scanner version 3.0 and describe a calibration method for capturing accurate spectral Stokes vector images with just one acquisition. Extraction of Muller matrix images of different non-destructive testing targets will then be presented.
