ABSTRACT:
A reflective liquid crystal light valve includes transparent conductive layers of indium tin oxide (30) employed as an electrode to electrically modulate orientation of molecules of a liquid crystal material that receives a high intensity reading light (40) applied through the transparent electrode. Unwanted double reflection (64,66) from interfaces between the indium tin oxide electrode (30) and adjacent layers (22,32) are minimized by application of broad band anti-reflective coatings (70,72,74,76) formed by one or more pairs of thin layers having alternately high and low indices of refraction.
