Here’s the future for marÂketÂing and adverÂtisÂers. ImagÂine disÂplayÂing holoÂgraphÂic prodÂucts that you can not only touch but will react with you. PicÂture a floatÂing can of Coca-Cola that you could grab and preÂtend to drink, or a crispy potaÂto chip you could place in your mouth. Read on, I’m telling you. Next levÂel media here, InterÂacÂtive holoÂgrams you can feel!
By now you all should know that holoÂgrams are a staÂple of sciÂence ficÂtion and go as far back to 1893, thanks to Jules Verne. Even recentÂly they have come into vogue due to develÂopÂments in lasers for enterÂtainÂment and award events. Researchers at DNG or the DigÂiÂtal Nature Group have found a way to use lasers, mirÂrors and camÂeras to creÂate three-dimenÂsionÂal, interÂacÂtive holoÂgrams comÂprised of tiny points of light called voxÂels. The team using femÂtosecÂond lasers (a femÂtosecÂond is a quadrillionth of a secÂond, and the lasers transÂmit bursts that last 30 to 270 femÂtosecÂonds), can make holoÂgrams that are safe to touch. The DNG researchers say earÂliÂer studÂies in creÂatÂing air plasÂma hadÂn’t achieved resÂoÂluÂtion this high, and would burn human skin.
The images are three-dimenÂsionÂal, with resÂoÂluÂtions up to 200,000 dots per secÂond. The voxÂels are light emitÂted by plasÂma that’s creÂatÂed when the laser’s focused enerÂgy ionÂizes the air. Yoichi OchiÂai a prinÂciÂpal invesÂtiÂgaÂtor in the experÂiÂments said when he touched the holoÂgram it felt like sandÂpaÂper, parÂticÂiÂpants thought the plasÂma felt a litÂtle like a staÂtÂic shock. OchiÂai was astoundÂed by how safe the plasÂma was to touch, conÂsidÂerÂing all the earÂliÂer attempts being harmÂful to skin.
The key to makÂing these holoÂgrams safe is the shortÂer duraÂtion of the laser’s bursts. In tests, if the lasers fired in more than two secÂond bursts, they burnt the leather researchers used to simÂuÂlate skin. But, if they transÂmitÂted at 50 milÂlisecÂonds to 1 secÂond bursts instead, the leather was unscathed.
Now what’s excepÂtionÂalÂly cool about this process is that since the lasers fire at such a high speeds, they’re able to react in real-time. They’ve testÂed its abilÂiÂty by makÂing usable holoÂgraphÂic checkÂboxÂes and hearts that break when touched. OchiÂai now says that his proof of conÂcept must be made bigÂger so they can make largÂer holoÂgrams. The curÂrent laser can transÂmit up to 7W, and this 1 cubic cenÂtimeÂter experÂiÂment only used 1W of the laser’s power.
HoloÂgraphÂic images you can touch and manipÂuÂlate; is this not thrilling. SoonÂer than you know adverÂtisÂing is going straight into the future.
