Development of an Electronic Holographic HMD Device
Ideal 3D image display
We are developing a head-mounted 3D display (HMD) device using electronic holography. This is a compact, lightweight and practical device realized by using a new computational algorithm and a newly designed optical system.
Content of research
Electronic holography-based display devices can display stress-free 3D images that are compatible with human visual physiology. Using computational correction, the head-mounted display (HMD) developed with this research replaces the complex optical system that had been required in the past, with a simple optical system. As a result, we have achieved the smallest and lightest electronic holography system in the world at low cost. As shown in the figure below, the hologram image can also be displayed to fit in the depth.
Unlike conventional HMDs, this HMD does not cause users stress due to a shift in depth focus.
Potential for social implementation
- ・Augmented reality 3D imaging equipment
- ・3D display device for 3D CAD
- ・3D video viewing equipment
Appealing points to industry and local governments
This electronic holography system is expected to be used not only for 3D image display systems, including 3D display in mechanical design such as CAD, and 3D model display in molecular design, but also for devices in various fields, including telemedicine systems, AR systems using HMD, 3D microscopes, 3D endoscopes, and even more advanced endoscopy surgery robots.
