French presidential candidate Jean - Luc Melenchon is extract out all the stops in the final days of the military campaign season , beaming a holographic image of his far - left subject matter to six cities across the land . There ’s only one problem with Melenchon ’s incredible technical feat : It ’s not in reality a hologram .
Melenchon used the same proficiency thatbrought Tupac back to lifeat Coachella in 2012 called “ Pepper ’s touch . ” It ’s a john that has been used since the 19th C by magicians and amusement parkland alike . The thaumaturgy essentially apply a special piece of glass that is both crystalline and reflective , meaning that it ’s capable to make a two - dimensional image appear to be float in gentle wind when light is bounce off the glass at the correct Angle .
In the modern era , this type of image can be manipulated with potent computers and projectors with super accurate accuracy , throw it look that someone is standing in the elbow room when they , in fact , are not . Although it ’s a neat john to see in person — it ’s not really a hologram .
This is n’t the same as a holograph because , by definition , is a three - dimensional image “ multiply from a pattern of preventative produced by a split lucid irradiation of radiation ( as a laser ) . ” In essence , this mean that a true hologram is an 3D image that can be seen without the aid of glasses or other intermediate optics like the paries of glass used in Melenchon ’s setup .
The modernistic definition of a holograph emerged in the former sixties shortly after the coming of laser technology , whenSoviet scientistYuri Denisyuk andUS scientistsEmmett Leith and Juris Upatnieks develop primitive 3-D holograph systems in tandem bicycle . accord toNature , Leith and Upatnieks “ used a optical maser and an off - axis of rotation configuration ” while Denisyuk used “ white twinkle as source ” to essentially receive the same answer .
Both teams were among the first to practice optical maser to display 3D images of static object without postulate any special glassful or other optics . Although former systems require high up - powered expensive speciality laser , novel systems are now taking advantage of aggregated - produceddiode laserslike the I used in DVD record-keeper . This technology is n’t wide used right now , though new “ volumetric displays ” like the one we checked out atLooking Glass Factorycould become more pop in the near hereafter .
By line , if you were to stand up really close to the Melenchon holograph setup — you’d see that the epitome is clearly two - dimensional . It ’s a very long way fromPrincess Leia ’s hologram messagein Star Wars : A New Hope .
Melenchon , 65 , is using the gimmick to help oneself himself stand up out in a extremely contentious Gallic election that set out on Sunday . Melenchon is pitted against conservative Francois Fillon , far - right candidate Marine Le Pen , and temperate Emmanuel Macron . Thepolls still showthat Macron is the deary to win , but Melenchon is surging agree to report card from theTelegraphandReuters . We imagine this is in part to appealing shtik like his fancy , albeit imitation , “ hologram . ” Let ’s see if voters still find out it impressive after hump they ’ve been befool by a 19th century conjurer ’s trick .
