Claim 0:
1. A method of calibration for an energy waveguide array, the energy waveguide array 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 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 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 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.
