1. A holographic energy system, comprising
a continuous three-dimensional energy medium;
an array of energy devices configured to output first energy operable to modify the continuous three-dimensional energy medium to define a hologram therein;
an electromagnetic energy source operable to output coherent EM energy to the continuous three-dimensional energy medium;
a controller operable to provide an instruction to the array of energy devices so that the hologram defined in the continuous three-dimensional energy medium modulates the coherent electromagnetic energy according to a complex amplitude function to generate a wavefront having a complex amplitude;
wherein the controller is further operable to dynamically update the instruction to the array of energy devices to update the hologram defined in the continuous three-dimensional energy medium to modulate the coherent electromagnetic Energy according to an updated complex amplitude function to generate a dynamically updated wavefront;
wherein the continuous three-dimensional energy medium comprises first and second immiscible phases;
wherein the first immiscible phase forms a first dispersion medium and the second immiscible phase forms a first dispersed phase in the first dispersion medium;
wherein the continuous three-dimensional energy medium comprises a third phase immiscible with the first and second immiscible phases of the continuous three-dimensional energy medium, wherein the third phase of the continuous three-dimensional energy medium forms a second dispersed medium; and
wherein the first dispersed phase is not dispersed in the third phase, and the continuous three-dimensional energy medium comprises a fourth phase immiscible with the first, second, and third phases of the continuous three-dimensional energy medium, and the fourth phase forms a second dispersed phase that is dispersed in the second dispersed medium.
