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 % [-]
