Claim 17:
18. A method of calibration for an energy directing system, wherein an energy relay element of the energy directing system is configured such that energy propagating through the energy relay element has higher transport efficiency in a longitudinal orientation, and an energy waveguide array of the energy directing system is operable to direct energy along uninhibited energy propagation paths extending from a first side to a second side of the energy waveguide array, wherein the uninhibited energy propagation paths extend, on the first side, to a plurality of relayed energy locations, and extend, on the second side, along different angular directions relative to the energy waveguide array depending on the respective energy locations on the first side the method comprising:
receiving data of energy attributes of energy at a plurality of relayed energy locations at a first surface of an energy relay element, wherein energy at the first plurality of energy locations was relayed from a plurality of source energy locations through the energy relay element along the longitudinal orientation; and
correlating predetermined data of energy attributes of energy at the plurality of source energy locations and the data of energy attributes of energy at the plurality of relayed energy locations to create a calibrated relay function, wherein the calibrated relay function comprises a mapping of the energy attributes at the first plurality of energy locations to the energy attributes at the second plurality of energy;
receiving data of energy attributes of energy along the uninhibited energy propagation paths on the second side of the waveguide array; and
correlating data of energy attributes of energy at the plurality of relayed energy locations and the data of energy attributes of energy along the uninhibited energy propagation paths on the second side of the waveguide array to create a calibrated four-dimensional (4D) plenoptic function for the energy waveguide array, wherein the calibration 4D plenoptic function comprises a mapping between the plurality of energy locations and the respective angular directions of the uninhibited energy propagation paths.
