Abstract:
A method for reconstructing an image from a total internal reflection hologram that includes the steps of:a) arranging the hologram in relation to the first face of a coupling body; b) generating a substantially collimated illumination beam; c) directing the illumination beam through a second face of the coupling body so that it reconstructs the image recorded in the hologram; d) recycling at least once the light in the illumination beam that does not reconstruct the image wherein the light reflected from the hologram is directed out of the coupling body through the second or a third face and is subsequently redirected as a recycled beam through the second face of the coupling body such that it also reconstructs the image recorded in the hologram; e) scanning the illumination and recycled beams across the hologram.
