1. A method for projecting a light field image comprising:
aligning each of a plurality of light field projectors in a projector array with an adjustment element;
receiving image data to the plurality of light field projectors in the projector array;
from each of the plurality of light field projectors, transmitting projected light rays to create a light field image, wherein creating the light field image comprises:
receiving the projected light rays at a collimating lens array comprising a plurality of collimating lenslets, each lenslet in the collimating lens array aligned with a corresponding light field projector in the projector array, and transmitting a collimated light beam from each lenslet;
diffusing the collimated light beam from each lenslet with a diffuser and transmitting diffused, collimated light beams; and
receiving the diffused, collimated light beams at a display lens and distributing the light beams according to a plenoptic sampling function; and projecting the light field image.
