Problems solved by technology
[0003] Although holographic 3D display is the most realistic 3D display and has great potential application prospects in the field of 3D display in the future, there are still some problems in the wavefront reconstruction of 3D display, one of which is when using a monochromatic extended light source to reproduce Easy to produce image blur (image blur) when imaging objects
In order to solve this problem, many solutions have been proposed. Among them, some researchers have proposed to use surface plasmons to suppress the image blur caused by the extended light source, but because the surface plasmon structure is in contact with the holographic recording dry plate, so It can only suppress the blurring of static 3D images, and cannot be practically applied to holographic dynamic 3D displays

Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings.
[0021] as attached figure 1 As shown, the dynamic holographic three-dimensional reconstruction device based on plasmonic nanostructures includes a common light source 1, a beam expander 2, a holographic recording medium layer 3 and a plasmonic nanostructure 5, and the light emitted by the common light source 1 passes through The beam expander 2 illuminates the holographic recording medium layer 3, and the light continues to transmit forward to the plasmonic nanostructure 5 to realize dynamic holographic reproduction.
[0022] The light emitted by the ordinary light source 1 passes through the beam expander 2 to form a beam with a certain divergence angle, which is irradiated on the holographic recording medium layer 3 to realize holographic reproduction. However, due to the multi-angle incident light of the reproduced light, the reproduced image is multiple The overla...

Abstract
The invention discloses a plasmon nanometer structure-based dynamic holographic three-dimensional reconstruction device, which comprises an ordinary light source, a beam expander, a holographic recording medium layer and a plasmon nanometer structure, wherein the holographic recording medium layer is irradiated by light emitted by the ordinary light source through the beam expanded, and the light is continuously transmitted forwards to the plasmon nanometer structure to realize dynamic holographic reconstruction. The device can be used for realizing dynamic holographic reconstruction, and image blur in a holographic reconstruction process is inhibited.
Description
technical field [0001] The present invention relates to holographic reproduction technology, in particular to a display device which uses a surface plasmon structure to realize dynamic holographic three-dimensional wavefront reconstruction and suppresses image blurring caused by the diffusion angle of a light source. Background technique [0002] The 3D display technology based on wavefront reconstruction truly reproduces the complex amplitude (including amplitude and phase) of the original scene light. It is a realistic 3D display that conforms to the viewing habits of the human eye, and is a forward-looking next-generation display technology. The representative implementation method of wavefront reconstruction is holography, that is, the wavefront information is optically written in the holographic recording material to generate a hologram, and then the hologram is irradiated with reproduced light to realize the three-dimensional reconstruction of the original scene.
