Movement Parallax3D Display Technology Based On Micro-lens Array

Three-dimensional display is widespread concerned and researched because ofsupplying large amount of vision informations and vivid watching experience.nowadays, head-mounted parallax3D display is developed, which leads toautostereoscopic display becoming the next researching hot point. Movementparallax3D display combined the advantages of traditional parallax3D display withholographic3D display, which not only owns improved3D vision but has a properdata size and simple structure. The core idea of this system is to joint discretesampling light field to construct the real object light field, which forms the watchingspace.However, current parallax3D display exists a series of drawbacks, like watchingangles limits and blurring problem comes from crosstalk. To solve these problems,some systemic analysis and theory research on movement parallax display based onmicro-lens array will be introduced in this thesis, which also could be presentedwhen considering about the system data amount. On the other hand, taking threedimensional information sampling process into account, the working mechanism ofprojection type parallax3D display based on micro-lens array will be investigated.As a result, two kinds of novel screen structures are proposed, they are multi-layerlenticular screen combined with curved diffuser structure and cylindrical lens arraycombined with retroreflection layer structure. Simulations and experimentsdemonstrates that the former multi-layer designs would give two timesimprovements on display imaging quality and display angle compare with thetraditional one, and the retrofeflection layer structure has potential of solving thecrosstalk problems respectively.Micro-structures, especially micro-lens array played an important role inautostereoscopic display system. The performance of3D display relays on thisstructure deadly. Thus, the processing technic of micro structure must be considered.in the last part of this thesis, the method of micro processing is discussed consideringabout the requirements of designed structure. we use the mask moving exposuretechnique to manufacture these micro structures, and ultraviolet(UV) imprinttechnology to transfer and assemble the final screen, which performs satisfied intesting experiments.
