Abstract
Holographic volume gratings in waveguide cells can be recorded using many different methods and systems in accordance with various embodiments of the invention. One embodiment includes a holographic recording system including at least one laser source configured to emit recording beams and a movable platform configured to move between a first position and a second position, wherein when the movable platform is in the first position, the at least one laser source is configured to emit a first set of one or more recording beams toward a first set of one or more stations and when the movable platform is in the second position, the at least one laser source is configured to emit a second set of one or more recording beams toward a second set of one or more stations.

11. A method for recording volume gratings, the method comprising:
-
emitting a first set of one or more recording beams using at least one laser source; directing the emitted first set of one or more recording beams toward a first set of one or more waveguide cells housed in a first set of one or more stations using at least one optical component mounted on a movable platform; recording a first set of one or more volume gratings in the first set of one or more waveguide cells; repositioning the movable platform; emitting a second set of one or more recording beams using the at least one laser source; directing the emitted second set of one or more recording beams toward a second set of one or more waveguide cells housed in a second set of one or more stations using the at least one optical component mounted on the movable platform; and recording a second set of one or more volume gratings in the second set of one or more waveguide cells. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. 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.
