“…where S1 is the difference between the horizontal and vertical polarization components, S2 is the difference between the polarization components in the direction of 45° and 135°, and S3 is the difference between the right-handed and left-handed circular polarization components. Henceforth the Mueller matrix can be calculated from the Stokes parameters of the incident and reflected light, enabling the measurement of physical characteristics such as the dielectric constant and refractive index [28].…”

The coded aperture correlation holography (COACH) is a powerful three-dimensional imaging technique. However, the conventional COACH method can only restore the three-dimensional images of the samples under test, but cannot specify the physical characteristics. We propose a full-dimensional measurement method based on the polarized coded aperture correlation holography. Specifically, the dynamic phase and geometric phase distributions can be separated from two holograms associated with the horizontal and vertical polarization components, then the Stokes parameters, surface topography and reflectivity can be calculated simultaneously. This method achieves the same spatial resolution for the two terms, which greatly improves the reliability and practicability with respect to conventional measurement methods.

“…8(a-c According to the method proposed in Ref. [28], the average refractive indexes of the feature region and the background region are worked out as 1.681 and 1.513, respectively. However, there is a large amount of noise in both the measured surface topography and the Stokes parameters.…”
