![]() The graphics very contiguous, sharp and clear. IMHO, science society was more advanced ~40 years ago when vector graphic displays were still a thing (Vectrex console, radar screens as computer displays, analog or hybrid oscilloscopes with CRTs and so on). Why can’t the technical minded society move on and open its mind? Use analogue or hybrid computers, too? IMHO, I think it’s a shame that we’re still mentally stuck thinking of binary computers, pixel-based displays such as LC displays, IPS/TN panels, and that fetisch for the latest/fastest GPU/CPU tech. What about laser technology? Long ago, my father heard of early holography experiments in the 1970s that used lasers. Of course these holograms also have some trouble with different colors of light at the same time for the same reason you get a rainbow looking at white light through a diffraction grating, and even aside from that light-wavelengh sized pixels are hard to produce as a digital medium. Of course the advantage is that you can actually have depth of field where lense focus matters in that case and you can examine minute and even microscopic details (up to the resolution allowed by the wavelength of light in use). That level of detail is somewhere around two orders of magnitude better than our highest DPI LCD’s and while I don’t want to say there isn’t another way to do it, it would require something really groundbreaking. With a laser hologram you are basically using a complex diffraction grating to recreate both the phase and direction of every single photon as it originally bounced off an object. Go check out the Looking Glass stuff if you want to see what light-field lenticular 3D can do with a decent number of angles represented… even if you aren’t actually interested in owning their stuff they have enough tech docs available that you can get a pretty good feel for how it works (TL dr a layer of pixels has several layers of lcd’s or similar that allow light to pass in some directions but not others, so you can form a series of flat images that project to enough different angles to fool your eyes). The image is in thin air, which can be achieved with lenticular 3D. Posted in News Tagged 3d display, hologram Post navigation Light field hacking isn’t exactly new, but this looks like it might be ready for prime time soon. If you want to learn more about traditional holograms, we’ve talked about them before. The company claims you will be able to see these in the real world as early as next year. We have no idea about cost, but imagine it won’t be cheap to start with. We couldn’t help but notice though, that the demo was in a dark place - it was made to look like an artistic choice, but we’ll bet that under bright lighting, they have difficulty delivering the image. The video shows that you can even use a magnifying glass to examine the object and it still looks real. It seems that while most displays try to project into a 3D volume or onto a flat display media, “solid light” works more like a real hologram, using a phase guide to project light at different phases and allows inference like an actual hologram. You can see a bit in the video below, but - of course - being on YouTube, you can’t get a sense for how good the 3D effect is. Has an interesting post about a startup company’s new holographic display that claims to be “indistinguishable from reality.” The company behind it, Light Field Labs, claims their system requires no glasses and handles different angles.
