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.
