How that would be done is way past me but the idea is similar to the original idea for Vivato Wireless&#8217; flat panel Wi-Fi antenna. That antenna concept, in its original incarnation, could steer multiple Wi-Fi beams simultaneously from one antenna. The flat panel used an electronically steerable phased-array concept to create several directional beams. Suppose there were 3 users out in a field &#8211; the antenna could create a directional beam independently yet simultaneously to each of the 3 users.<\/p>\n<p>If we can do this at radio frequencies, I thought, perhaps there is a way to do this at optical frequencies.<\/p>\n<p>The description of this HP invention sounds similar (but could also be completely different). Their invention demonstrates glasses free, full color 3D displays.<\/p>\n<h6 class=\"zemanta-related-title\" style=\"font-size: 1em;\">Related articles<\/h6>\n<ul class=\"zemanta-article-ul zemanta-article-ul-image\" style=\"margin: 0; padding: 0; overflow: hidden;\">\n<li class=\"zemanta-article-ul-li-image zemanta-article-ul-li\" style=\"padding: 0; background: none; list-style: none; display: block; float: left; vertical-align: top; text-align: left; width: 84px; font-size: 11px; margin: 2px 10px 10px 2px;\"><a style=\"box-shadow: 0px 0px 4px #999; padding: 2px; display: block; border-radius: 2px; text-decoration: none;\" href=\"http:\/\/nextbigfuture.com\/2013\/03\/optical-trickery-lets-modified-lcd.html\" target=\"_blank\" rel=\"noopener noreferrer\"><img decoding=\"async\" style=\"padding: 0; margin: 0; border: 0; display: block; width: 80px; max-width: 100%;\" alt=\"\" src=\"http:\/\/i.zemanta.com\/153806581_80_80.jpg\" \/><\/a><a style=\"display: block; overflow: hidden; text-decoration: none; line-height: 12pt; height: 80px; padding: 5px 2px 0 2px;\" href=\"http:\/\/nextbigfuture.com\/2013\/03\/optical-trickery-lets-modified-lcd.html\" target=\"_blank\" rel=\"noopener noreferrer\">Optical trickery lets a modified LCD produce hologram-like still images and videos at 127 dots per inch and appears to be a path to practical nearterm commercial 3D displays<\/a><\/li>\n<li class=\"zemanta-article-ul-li-image zemanta-article-ul-li\" style=\"padding: 0; background: none; list-style: none; display: block; float: left; vertical-align: top; text-align: left; width: 84px; font-size: 11px; margin: 2px 10px 10px 2px;\"><a style=\"box-shadow: 0px 0px 4px #999; padding: 2px; display: block; border-radius: 2px; text-decoration: none;\" href=\"http:\/\/www.theverge.com\/2013\/3\/20\/4128808\/hp-labs-developing-a-holographic-3d-display\" target=\"_blank\" rel=\"noopener noreferrer\"><img decoding=\"async\" style=\"padding: 0; margin: 0; border: 0; display: block; width: 80px; max-width: 100%;\" alt=\"\" src=\"http:\/\/i.zemanta.com\/153811420_80_80.jpg\" \/><\/a><a style=\"display: block; overflow: hidden; text-decoration: none; line-height: 12pt; height: 80px; padding: 5px 2px 0 2px;\" href=\"http:\/\/www.theverge.com\/2013\/3\/20\/4128808\/hp-labs-developing-a-holographic-3d-display\" target=\"_blank\" rel=\"noopener noreferrer\">HP Labs developing a holographic 3D display with a 180-degree viewing zone<\/a><\/li>\n<\/ul>\n<div class=\"zemanta-pixie\" style=\"margin-top: 10px; height: 15px;\"><a class=\"zemanta-pixie-a\" title=\"Enhanced by Zemanta\" href=\"http:\/\/www.zemanta.com\/?px\"><img decoding=\"async\" class=\"zemanta-pixie-img\" style=\"border: none; float: right;\" alt=\"Enhanced by Zemanta\" src=\"http:\/\/img.zemanta.com\/zemified_e.png?x-id=e5bc8232-48c3-4957-b114-aa61f8adbf27\" \/><\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>A multi-directional backlight for a wide-angle, glasses-free three-dimensional display : Nature : Nature Publishing Group.
