Talk of generative AI and language models were naturally going to dominate this year, and they did. But glasses-free immersive 3D was one of the biggest CES ’25 trends. What this means in each ...
The 3D image from a hologram can often be viewed with non-laser light. However, in common practice, major image quality compromises are made to remove the need for laser illumination to view the hologram. A computer-generated hologram is created by digitally modeling and combining two wavefronts to generate an interference pattern image.
It involves generating holographic interference patterns. A computer-generated hologram can be displayed on a dynamic holographic display, or it can be printed onto a mask or film using lithography. [1] When a hologram is printed onto a mask or film, it is then illuminated by a coherent light source to display the holographic images.
It is possible to make holograms of much less stable objects by using a pulsed laser which produces a large amount of energy in a very short time (μs or less). [7] These systems have been used to produce holograms of live people. A holographic portrait of Dennis Gabor was produced in 1971 using a pulsed ruby laser. [1]: Figure 4.5, p44 [8]
The Proto Luma, Proto’s latest innovation, powers the HMN network. Designed for retail, the Luma is more compact and cost-effective than Proto’s flagship Epic, while still delivering vivid 3D holograms. Its integration with Proto’s proprietary AI Persona tools and RetailSage fleet management system ensures seamless operation at scale.
Voxon Photonics' 3D holograms use similar displays to a 3D printer and then the human eye does the rest. The post Australian-based company launches device that can project 3D holograms appeared ...
So far, the only true color hologram we've seen come from a tiny, complicated display created by a Korean group led by LG, while the rest are just "Pepper's Ghost" style illusions.
A holographic display is a type of 3D display that utilizes light diffraction to display a three-dimensional image to the viewer. Holographic displays are distinguished from other forms of 3D displays in that they do not require the viewer to wear any special glasses or use external equipment to be able to see the image, and do not cause a vergence-accommodation conflict.
