Abstract

We present a method for measuring all eight parameters in- cluding the signs of the Jones matrices of liquid-crystal displays. The method can be applied to measure the Jones matrices for all address- able gray levels thus delivering the specifications needed for calculating characteristic curves for arbitrary input and output polarizations. Unlike other approaches, we do not rely on a physical model of the LCD. Thus, it is possible to measure the Jones matrices of a more complex optical system in one step e.g., when a reflective LCD is used in combination with a beamsplitter. Though the method presented is, in principle, appli- cable for transmissive and reflective LCDs, calculations and experiments are only shown using the example of a reflective liquid-crystal-on-silicon
