Abstract
A holographic energy system is operable to generate an output wavefront according to a complex amplitude function. The holographic energy system includes a continuous three-dimensional energy medium, an array of energy devices configured to output energy to interact with the continuous three-dimensional energy medium to define a hologram therein, and an electromagnetic (EM) energy source positioned to output coherent EM energy that is incident on the hologram in the continuous three-dimensional energy medium to generate an output wavefront.
