Abstract

The depolarization of a TVT-6000 liquid-crystal television has been measured to vary between 2% and 9% as a function of bias voltage, angle of incidence, and incident polarization state.

Fraction of transmitted light that is unpolarized for three incident polarizations: (a) horizontal, (b) 45°, (c) left circular. FU is plotted as a function of angle of incidence (left to right) and applied voltage (bottom to top).

Configuration of the Mueller-matrix imaging polarimeter. Utilizing rotating retarders and a 14-bit CCD camera, the polarimeter measures a series of 60 images to obtain a Mueller-matrix image. Accuracy is better than 1% at 632.8 nm. The instrument is entirely automated by a PC.

Mueller-matrix images of the TVT-6000 LCTV as a function of angle of incidence and applied voltage. The Mueller matrices relate the input and output polarization states for arbitrary incident polarizations. These Mueller-matrix images contain the depolarization, retardance, and diattenuation and their variation over the field.

Retardance of the LCTV as a function of angle of incidence and applied voltage: (a) horizontal component of linear retardance δ0, (b) 45° component of linear retardance δ45, (c) circular retardance δR. The net retardance is elliptical, and its magnitude is nearly linear in applied voltage and angle of incidence.
