Abstract
A near-eye light field display device includes a plurality of sub-aperture light field emitting modules and a bi-telecentric lens group. The plurality of sub-aperture light field emitting modules are adapted to generate a plurality of sub-aperture light fields. The bi-telecentric lens group is disposed on one side of the plurality of sub-aperture light field emitting modules, wherein the plurality of sub-aperture light fields pass through the bi-telecentric lens group and are converted into an exit light field by the bi-telecentric lens group, and the exit light field is incident on a receiver.
Claims19
A near-eye light field display device, comprising:
- a plurality of sub-aperture light field emitting modules, wherein the plurality of sub-aperture light field emitting modules are adapted to simultaneously generate a plurality of sub-aperture light fields, and wherein fields of view of sub-images of the plurality of sub-aperture light fields are essentially the same;
- a bi-telecentric lens group, disposed on one side of the plurality of sub-aperture light field emitting modules, wherein the plurality of sub-aperture light fields simultaneously pass through the bi-telecentric lens group and are converted into an exit light field by the bi-telecentric lens group, and the exit light field is incident on a receiver, and wherein a field of view of the exit light field is essentially the same as the fields of view of the sub-images of the plurality of sub-aperture light fields.
A head mounted display device, comprising:
- two near-eye light field display devices, wherein each near-eye light field display device comprises a plurality of sub-aperture light field emitting modules and a bi-telecentric lens group, the plurality of sub-aperture light field emitting modules are adapted to simultaneously generate a plurality of sub-aperture light fields, wherein fields of view of sub-images of the plurality of sub-aperture light fields are essentially the same, the bi-telecentric lens group is disposed on one side of the plurality of sub-aperture light field emitting modules, the plurality of sub-aperture light fields simultaneously pass through the bi-telecentric lens group and are converted into an exit light field by the bi-telecentric lens group, and the exit light field is incident on a receiver, wherein a field of view of the exit light field is essentially the same as the fields of view of the sub-images of the plurality of sub-aperture light fields.
