摘要

We propose a see-through additive light field display as a novel typernof compressive light field display. We utilize holographic optical elementsrn(HOEs) as transparent additive layers. The HOE layers arernalmost free from diffraction unlike spatial light modulator layers,rnwhich makes this additive light field display more advantageousrnwhen modifying the number of layers, thickness, and pixel densityrncompared with conventional compressive displays. Meanwhile,rnthe additive light field display maintains advantages of compressivernlight field displays. The proposed additive light field display showsrnbright and full-color volumetric images in high definition. In addition,rnusers can view real-world scenes beyond the displays. Hence,rnwe expect that our method can contribute to the realization of augmentedrnreality. Here, we describe implementation of a prototypernadditive light field display with two additive layers, evaluate thernperformance of transparent HOE layers, describe several results ofrndisplay experiments, discuss the diffraction effect of spatial lightrnmodulators, and analyze the ability of the additive light field displayrnto express uncorrelated light fields.
