We developed high efficiency see-through glasses in a compact structure using waveguides and embedded coupling wavelength selective filters. The design provides a solution for the optical combiner offering high see-through transparency and high luminance image with low loss. A prototype of the see-through glasses based on the proposed design was fabricated and the optical properties were measured by experiments. Through the prototype, both the overlaid virtual image and the real ambient view can be seen with high resolution.
To meet the increasing demand for the dynamic naked-eye 3D display, we proposed a new method to realize the dynamic effect of hologram by using the holographic printing technology. We used a convergent light as the object beam to print out a holographic plate through point-by-point exposure inside a photopolymer material. In reproduction, an image processed by two view images of a 3D object was directly projected to the holographic plate as reconstruction beam, and two images were observed from different directions. That is, when we project an image containing several views of a 3D object, based on multi-view principle, we can observe the reconstructed 3D effect. Since the display plate doesn’t carry amplitude information, the content of reproduced 3D image depends on that of the projected image. Thus, a dynamic stereo effect can be achieved by projecting each image processed from a frame of dynamic stereo continuously
