“…From the 3×3 submatrix m′ , the depolarization Mueller matrices M Δ (g) were obtained through Eqs. (7) and (10). Figure 2(a) shows the experimental values for the depolarization power, Δ(g), calculated in accordance with Eq.…”

“…Then, the state of polarization (SoP) is not described by the complex amplitudes of the electric field but by the corresponding Stokes vector. Experimental Mueller matrices of a LCoS cell have been measured with several polarimetric techniques [10,11]. Between them, it should be mentioned those based on nematic liquid crystal variable retarders [11].…”

Abstract:We provide experimental measurement of the Mueller matrices corresponding to an on-state liquid-crystal-on-silicon display as a function of the addressed voltage. The polar decomposition of the Mueller matrices determines the polarization properties of the device in terms of a diattenuation, a retardance and a depolarization effect. Although the diattenuation effect is shown to be negligible for the display, the behavior of the degree of polarization as a function of the input polarization state shows a maximum coupling of linearly polarized light into unpolarized light of about 10%. Concerning the retardation effect, we find that the display behaves as a retarder with a fast-axis orientation and a retardance angle that are voltage-dependent. The above decomposition provides a convenient framework to optimize the optical response of the display for achieving a phase-mostly modulation regime. To this end, the display is sandwiched between a polarization state generator and a polarization state analyzer. Laboratory results for a commercial panel show a phase modulation depth of 360º at 633 nm with a residual intensity variation lower than 6 %.

“…In the calculation, the LC droplet can be considered as a composite of thin slices, which is a single birefringent element (Kitzerow, 1994). Because the retarders are generated from the single birefringent plate, the polarization properties show moderately linear correlation with the retardance of wavelength (Pezzaniti and Chipman, 1995;Chipman and Bass, 1995); therefore the degree of polarization can be evaluated as a function of wavelength retardance, which is shown in Fig. 4.…”

“…In this case, a uniform input 45° linear polarization exits the system with some nonuniformity and finite ellipticity caused by a relative phase shift between S and P polarization of 2.5 to 3.2 degrees, but the pupil-averaged output angle is only rotated by 0.1° to 0.2°. The next step in the design validation is to measure Mueller matrices of various first mirror surface materials as a function of wavelength and angle of incidence, and use these in a more complete polarization ray trace in Code V. These measurements will be made by a Mueller matrix angle of incidence imaging polarimeter [9]. Two example mirror candidates have already been checked using this technique for a limited number of angles.…”

Abstract. The advanced tokamak research program at DIII-D relies critically on the measurement of the current density profile. This was made possible by the development of a Motional Stark Effect (MSE) polarimeter that was first installed in 1992. Three major upgrades have since occurred, and improvements in our understanding of critical performance issues and calibration techniques are ongoing. In parallel with these improvements, we have drawn on our DIII-D experience to begin studies and design work for MSE on burning plasmas and ITER. This paper first reviews how Motional Stark Effect polarimetry (MSE) is used to determine the tokamak current profile. It uses the DIII-D MSE system as an example, and shows results from the latest upgrade that incorporates an array of channels from a new counter-Ip injected neutral beam. The various calibration techniques presently used are reviewed. High-leverage or unresolved issues affecting MSE performance and reliability in ITER are discussed. Next, we show a four-mirror collection optics design for the two ITER MSE views. Finally, we discuss measurements of the polarization properties of a few candidate mirrors for the ITER MSE.
