What are Volumetric and Holographic Displays?

One of the long anticipated innovations to stem from the rapid progression of technology has been holographic or volumetric displays, also referred to as 3D displays. Since 2005, researchers have been working toward creating practical uses for holography, and the aggregated attempts of these developers over the years have turned 3D visuals into an experience that can be facilitated by a personal mobile device. MIT's Media Lab produced a holographic projector that employs a spatial light modulator (SLM), the central component of digital holography, to create a holographic video. As these technologies continue to be refined, it won't be long before consumers will have the option of purchasing devices with holographic capabilities, an advancement that will be accompanied by a offering of downloadable media files in 3D formats.

(1) How might this technology be relevant to the educational sector you know best?

  • another type of VR and visualization technology- len.scrogan len.scrogan Apr 11, 2016
  • There are many variations in this entire field; these are all visualization technologies, but they are strangely split and separated throughout this Horizon editing process. It includes spherical 3D, 360 3D and 360 photography (Google Expeditions, btw), visualization walls, caves, hives, domes, semi-domes, and 3D projectors/displays. These tools and technologies continue to merge, divide, subdivide, and morph as the technologies involved improve. Not sure they should be separated as we have done here. They are all related, all visualization technologies, chasing a future.- len.scrogan len.scrogan Apr 11, 2016 - davidwdeeds davidwdeeds Apr 25, 2016
