First Claim
1. An adaptive plasma optics cell comprising:
- a housing defining a chamber;
a gas disposed within the housing chamber;
a first light transmissive electrode layer coupled to a first side of the housing;
a first light transmissive dielectric layer coupled between the first light transmissive electrode layer and the housing chamber;
a second electrode layer coupled to a second side of the housing such that the housing chamber is at least partially disposed between the first and second electrode layers;
a second dielectric layer coupled between the second electrode layer electrode and the housing chamber;
a power supply coupled to each of the first and second electrode layers and adapted to supply an electric signal sufficient to cause the gas to generate a plasma having a first plasma gradient; and
a controller coupled to the power supply and adapted to adjust the electric signal supplied to the first and second electrode layers to cause the gas to generate a plasma having a second plasma gradient different than the first plasma gradient,wherein when a light passes through the generated plasma, the first plasma gradient causes the light to refract at a first angle, and the second plasma gradient causes the light to refract at a second angle.

Abstract
An adaptive plasma optics cell includes a housing defining a chamber, and a gas disposed within the housing chamber. A first light transmissive electrode layer is coupled to a first side of the housing and a first light transmissive dielectric layer is coupled between the first light transmissive electrode layer and the housing chamber. A second electrode layer is coupled to a second side of the housing such that the housing chamber is at least partially disposed between the first and second electrode layers and a second dielectric layer coupled between the second electrode layer electrode and the housing chamber. In operation, a power supply is controlled such that the power supply selectively supplies an electric signal sufficient to cause the gas to generate a plasma having a desired plasma gradient.
