CONFIGURABLE ADAPTIVE OPTICAL MATERIAL AND DEVICE
Techniques associated with an adaptive optical material and device are described, including a device having a layer, a substrate, and an intermediate layer disposed between the substrate and the layer. The intermediate layer may include a first bladder and a second bladder. Each bladder may have a surface portion associated with an intermediate layer and another surface portion associated with a substrate. A first bladder may receive a first volume of fluid to form a first distance between the surface portions, and a first bladder may receive a second volume of fluid to form a second distance between the surface portions. A portion of a surface of the layer may include a degree of curvature relative to a line perpendicular to the substrate based on a difference between the first distance and the second distance. The degree of curvature may focus a subset of collimated light rays substantially at a point.
