METHOD AND APPARATUS FOR CREATION AND ELECTRICAL TUNING OF SPATIALLY NON-UNIFORM REFLECTION OF LIGHT |
| 摘要 |
A variable optical device for controlling properties of reflected light is described. The device includes a light reflecting surface, a layer of dynamically controllable material and an excitation source for generating an excitation field acting on the layer of dynamically controllable material. An electrical drive signal applied to the excitation source causes a change of optical properties in the layer of dynamically controllable material to provide a spatially varying change in light reflection having at least one of a desired phase curvature and a desired amplitude modulation profile. |

1. A variable optical device for controlling properties of reflected light, the device comprising:
a light reflecting structure; a layer of continuous non-pixelated dynamically controllable material including one of a liquid crystal mixture and a polymer composite; and an excitation source for generating an excitation field acting on said layer of dynamically controllable material having a variable index of refraction sensitive to said excitation field, wherein an electrical drive signal applied to said excitation source causes a change of optical properties in said layer of dynamically controllable material to provide a spatially varying change in light reflection having at least one of a desired phase curvature and a desired amplitude modulation profile. |
