14. A holographic recording system comprising:
-
a laser source; first, second, third, and fourth stations, wherein each station comprises an exposure stack and a waveguide cell stage, wherein the waveguide cell stage is configured to; house a waveguide cell; position the waveguide cell such that a surface of the waveguide cell is parallel to a surface of the exposure stack; and maintain the position of the waveguide cell while accounting for micro-movements; a pair of stationary beamsplitters; a movable platform mounted on a track, wherein the movable platform is configured to move along the track between a first position and a second position; three beamsplitters mounted on the movable platform, wherein; when the movable platform is in the first position, the laser source is configured to; emit a first set of six recording sub-beams simultaneously by; emitting a first initial recording beam toward the pair of stationary beamsplitters to form a first set of three recording beams; and directing the first set of three recording beams toward the three mounted beamsplitters to form the first set of six recording sub-beams; direct three recording sub-beams within the first set of the six recording sub-beams toward the first station; and direct the other three recording sub-beams within the first set of six recording sub-beams toward the second station; and when the movable platform is in the second position, the laser source is configured to; emit a second set of six recording sub-beams simultaneously by; emitting a second initial recording beam toward the pair of stationary beamsplitters to form a second set of three recording beams; and directing the second set of three recording beams toward the three mounted beamsplitters to form the second set of six recording sub-beams; direct three recording sub-beams within the second set of the six recording sub-beams toward the third station; and direct the other three recording sub-beams within the second set of six recording sub-beams toward the fourth station.
