In general, a linearly polarized wave can be changed into an elliptically or circularly polarized wave by using a wave polarizer. However, adding an external polarizer will increase the size and complexity of the antenna. In this patent, a polarizer is directly integrated with the omnidirectional LP.....

The invention presents a novel means for generating and displaying images that appear to be floating in the air. A single image or a sequence of images can be converted into an animated sequence of 3D images. Disparity information is present in the images to provide depth perception, which can be co.....

The display of digital holograms is hampered by the fact that the resolution of existing display media is usually lower than the wavelength of light. To solve the problem, the generation of full parallel digital Fresnel holograms is developed to make possible their display on specially designed low .....
