Light Field Lab: Startup is Working on Glasses-Free Holographic TV Sets

Light Field Lab: Startup is Working on Glasses-Free Holographic TV Sets using Light FIeld Tech (picture: Light Field Lab) At this week’s National Association of Broadcasters (NAB) show in Las Vegas, a startup named Light Field Lab has announced they’re developing the next big thing in display technology: glasses-free holographic TVs.
Founded by former Lytro specialists Jon Karafin (former Head of Light Field Video at Lytro), Brendan Bevensee (former Lead Engineer at Lytro) and Ed Ibe (former Lead Hardware Engineer at Lytro), the company is working on the “next generation of light field display technologies”. Continue reading

Lytro Immerge becomes Bigger and Better

Lytro Immerge becomes Bigger and Better (photo: Road to VR) Back in August 2016, Lytro unveiled its first Virtual Reality experience, “Moon” (see below), to show off the capabilities of Immerge, the company’s groundbreaking, high-end production camera that records light fields for virtual reality. While it was reportedly an impressive experience for the VR viewer, it also had its limitations (especially with moving objects in the recorded scene).
Now, Ben Lang from RoadToVR talks about a recent visit to Lytro, where he saw the new and improved Immerge prototype. Continue reading

Light Field Powered: First Smartphones with Holographic Displays Could Arrive within Two Years

Ostendo's Quantum Photonic Imager Chips produce real 3D images with depth (top: resulting image with diffuser, bottom: actual QPI array; Youtube Screenshot via InsightMediaTV1) Just a few years ago, mobile displays took a leap forward with increased pixel densities that ensure crisp images on realtively small screens. Today, most smartphones feature displays with up to 538 pixels per inch (ppi) – a resolution that is much higher than what the human eye can see. So what’s the next display innovation we can look forward to?
In her recent article on IEEE Spectrum, Sarah Lewin introduced two companies that are working on making what she calls “holographic” light field displays (i.e. glasses-free 3D displays) a reality.

Ostendo Technologies recently presented the results of nine years’ work at the Display Week conference: An array of 4×2 Quantum Photonic Imager chips (each consisting of LEDs, image processors and embedded rendering software) plus microlens array form a 1 megapixel (1024x768px, XGA resolution) prototype display which sends out light not into every direction – like conventional displays do – but rather into very narrow, collimated angles of light. This enables the prototype to emit different images into different directions, producing about 2,500 different perspective views, so the image and motion displayed appear consistent regardless of the viewer’s position.

Pinlight Display: Light Field Glasses for Augmented-Reality Applications

Nvidia Pinlight Display: Light Field Glasses for Augmented-Reality Applications (picture: Siggraph 2014 website) Earlier this year at Augmented World Expo, Nvidia researcher Douglas Lanman gave a talk about Near-Eye Light Field displays, i.e. electronic glasses which allow users to experience both 3D and depth. When asked about Augmented Reality (AR) applications during the discussion, Lanman noted that creating a set of transparent glasses that would also include microlenses (or something equivalent) but still allow “normal” see-through vision, was a real challenge. He very briefly teased “pinlight displays”, which were to be presented at the same conference, but no further information could be found online.

In the Emerging Technologies section of the Siggraph 2014 conference (10-14 August 2014), Adam Maimone and colleagues from the University of North Carolina at Chapel Hill and Nvidia will be presenting their new invention in a talk entitled “Pinlight Displays: Wide-Field-of-View Augmented-Reality Eyeglasses Using Defocused Point-Light Sources”.

Nvidia Near-Eye Light Field Display: Background, Design and History [Video]

Nvidia Near-Eye Light Field Display: Binocular OLED-based prototype (Youtube Screenshot) About a year ago, Nvidia presented a novel head-mounted display that is based on light field technology and offers both depth and refocus capability to the human eye. Their so-called Near-Eye Light Field Display was more a proof of concept, but it’s exciting new technology that solves a number of existing problems with stereoscopic virtual reality glasses.

Nvidia researcher Douglas Lanman recently gave a talk at Augmented World Expo (AWE2014), in which he explained the background and evolution of head-mounted displays and the history and design of Nvidia’s near-eye light field display prototypes: Continue reading
