Abstract: Techniques and assemblies for light ray steering are described. A method for directing light rays includes steering the light rays using a static prism and controllably steering the light rays using an electro-optic prism, such that the combination of the light ray steerings from the static prism and the electro-optic prism substantially steer the light rays to impinge on a light focusing element at a predetermined angle. The electro-optic prism includes a first electrode positioned on a first substrate, a second electrode positioned on a second substrate, and an electro-optic material positioned between the first and second electrodes. The first electrode includes multiple substantially parallel linear electrodes. Applying multiple voltages to some or all of the multiple substantially parallel linear electrodes generates a refractive index gradient across the electro-optic prism. The direction of solar rays exiting the electro-optic prism is controllable by controlling the refractive index gradient.

Abstract: Techniques and assemblies for steering light rays are described. An electro-optic prism is operable to provide controllable steering of light rays. The electro-optic prism includes a first electrode including multiple substantially parallel linear electrodes on a first substrate and a reference electrode on a second substrate. An electro-optic material is positioned between the first electrode and the reference electrode. When separately controllable voltages are provided to at least some of the linear electrodes, a gradient electric field is provided within the electro-optic material to cause the electro-optic material to have a refractive index gradient. The refractive index gradient can be controlled by varying the magnitude of the separately controllable voltages provided to at least some of the linear electrodes.

Abstract: Techniques and assemblies for steering light rays are described. An electro-optic prism is operable to provide controllable steering of solar rays. The electro-optic prism includes a first electrode, a reference electrode and an electro-optic material positioned between the first and reference electrodes. In one implementation, the first electrode includes multiple substantially parallel linear electrodes positioned on a first substrate and the reference electrode is positioned on a second substrate. Such implementation can include that when separately controllable voltages are provided to at least some of the linear electrodes, a gradient electric field is provided within the electro-optic material to cause the electro-optic material to have a refractive index gradient. The refractive index gradient can be controlled by varying the magnitude of the separately controllable voltages provided to at least some of the linear electrodes.

Abstract: The present invention generally relates to an electro-active optic incorporating a blend region between two regions each having different optical properties.
