Holograms Enter Political Communication

A new pilot initiative at an airport in Jacksonville has demonstrated the emerging role of holographic technology in public communication, marking a significant step toward the integration of immersive media in political engagement. Using advanced display systems developed by companies such as Proto, a life-sized hologram of the city’s mayor was installed to deliver messages to travelers. The system supports both pre-recorded and interactive formats, showcasing the potential for public officials to extend their presence across multiple locations simultaneously and communicate at scale without the need for physical travel.

The deployment highlights both the opportunities and challenges associated with this technological shift. Proponents emphasize increased accessibility, efficiency, and the ability to reach broader audiences in real time. However, concerns have been raised regarding authenticity, trust, and the implications of AI-enhanced interactions in political contexts. As holographic and AI-driven communication tools continue to evolve, this initiative serves as an early case study in how emerging technologies may reshape the relationship between public figures and citizens, prompting important discussions about transparency, ethics, and the future of democratic engagement.

Holographic Ultrasound Printing

Researchers at Concordia have developed a novel method of 3D printing that uses acoustic holograms. And they say it’s quicker than existing methods and capable of making more complex objects. The process, called holographic direct sound printing (HDSP).

Now, by embedding the technique in acoustic holograms that contain cross-sectional images of a particular design, polymerization occurs much more quickly. It can create objects simultaneously rather than voxel-by-voxel.

iPhone Holographic Projector

Researchers have created a two-layer optical reproduction of a full-color 3D image by displaying one holographic layer on the screen of an iPhone 14 Pro and a second layer on a spatial light modulator. The resulting image measured a few millimeters on each side.

They are now working to improve the technology so that it can display larger 3D images with more layers. Additional layers would make images look more realistic by improving spatial resolution and allowing objects to appear at several different depths, or distances, from the viewer.

3D Holographic Displays Based on Deep Learning

A team of researchers from Chiba University propose a novel approach based on deep learning that further streamlines hologram generation by producing 3D images directly from regular 2D color images captured using ordinary cameras. The proposed approach employs three deep neural networks (DNNs) to transform a regular 2D color image into data that can be used to display a 3D scene or object as a hologram. The first DNN makes use of a color image captured using a regular camera as the input and then predicts the associated depth map, providing information about the 3D structure of the image. Both the original RGB image and the depth map created by the first DNN are then utilized by the second DNN to generate a hologram. 

The third DNN refines the hologram generated by the second DNN, making it suitable for display on different devices. The researchers found that the time taken by the proposed approach to process data and generate a hologram was superior to that of a state-of-the-art graphics processing unit. Soon, this approach can find potential applications in heads-up and head-mounted displays for generating high-fidelity 3D displays. Likewise, it can revolutionize the generation of an in-vehicle holographic head-up display, which may be able to present the necessary information on people, roads, and signs to passengers in 3D. The proposed approach is thus expected to pave the way for augmenting the development of ubiquitous holographic technology.
