Pixel-based Holographic Recording And High Resolution Multi-view Three-dimensional Restruction Of Image

Multi-view three-dimensional imaging technology can display a different image ona different direction, allowing the viewer to see different images having differentviewpoints in a plurality of directions. Horizontal-parallax-only imaging modalities intoa multi-angle image only in the horizontal direction. However, increasing the number ofimages displayed on the two-dimensional display equipment, single image resolution willdecrease. The volume holographic recording material having the ability to anglemultiplexing, the images recorded at different angles. Holographic pixel-based imagewriting method using a simple translation, to write the angle multiplexed images.To make the single image resolution is not reduced when increasing the number ofrecording images. Holographic material which has excellent angle multiplexing capability,was used to record and display images. The holographic material, Polyvinyl-Acrylamideis produced, the photosensitive sensitivity to67.7mJ/cm2, the diffraction efficiency was18.1%. Holographic pixel-based image writing method is used to record the slice-images,the results of reproduce can display the horizontal-parallax-only imaging. This methodusing a simple translation to write the angle multiplexed images. Simplified the operationof angle multiplexing image writing. Verified using the volume hologram recordingmaterial in horizontal-parallax-only imaging method, the single image resolution is notreduced when increasing the number of recording images.To further improve the resolution of the reproduced image, the angle-multiplexedholographic recording material capacity is fully utilized. Holographic pixels areoverlapped parts. Development processing of the original images. The original imageswas divided into slice images, and then according to the horizontal-parallax-only imagingtheory stitch slice images, to get holographic pixel images. Use computer programprocessing original images, holographic pixel images obtained. In the ordinaryholographic pixel-based image writing method, holographic pixels are not overlapped atall. Pixel pitch of the display image is large, and has low resolution. After partiallyoverlapping exposure position, narrowing the distance between two pixels adjacent insingle image, the resolution of the image display increased. Resolution of image displayreaches200pixels per inch.
