Abstract

Referring to Figure 1, an image bar 10 is formed by placing one or more electrodes 12 on a light-transmitting substrate 14. With no voltage applied to the electrodes, light is transmitted through an entrance port 16 to an exit port 18. When a voltage is applied to the electrode (Figure 2), the refractive index of the substrate is changed. Light is refracted during passage through the substrate and is blocked by an occluder 20 adjacent the exit port.
