French Politician Uses Hologram To Hold Meetings In Two Cities At the Same Time (reuters.com)
neutrino38 writes: The French presidential election is approaching fast. One of the candidates, Jean-Luc Melenchon, used a hologram to hold two public meetings at once. With a political program that is mostly socialist and very left leaning, some people pointed out that he used private innovation to stand out from the crowd. Reuters notes that this is "not the first politician to employ such technology," adding that "in 2014, then-Turkish prime minister Tayyip Erdogan used a huge hologram of himself to attract wider support, while India's Narendra Modi trounced the opposition with a campaign that included holograms of his speeches in villages across the country." You can watch part of one of Melenchon's virtual meetings here.

Somebody please explain the significance of selected statement here. Does being a candidate of the Socialist Party mean that one should be coy like a little princess? Isn't that equivalent to using alien technology for a politician?
Has anyone ever seen this guy and Palpatine in the same room together?
Can we go easy on the word 'Hologram'? This is likely a pepper's ghost effect; as is 90%+ of what's being called a 'hologram' these days.
It's a neat effect, and the Reuters image reveals a great reference for the setup (particularly interesting lighting rig), but lets reserve the h word for real examples of the phenomenon.
Marketers seem eager to abuse and misuse establish terms for advertising purposes. First "hoverboard", now "hologram".
As best as I can tell (TFA is devoid of details), this is a glorified version of the system used at Hatsune Miku" concerts - a simple rear projection onto a glass screen. A slightly more sophisticated version uses multiple cameras surrounding the person whose image is being broadcast, and switches between them depending on where the observer camera is positioned. That creates the illusion that the observer can move around the image in 3D, but the illusion only works for the observer being tracked. Anyone else sees a 2D image which rotates depending on where the designated observer moves, not based on where they themselves move.
A true hologram is not conveyed as an image. It is conveyed as an interference pattern created by taking a Fourier transform of a 3D light field. When you take another Fourier transform of that interference pattern (e.g. shine onto it coherent light equivalent to the light that originally created the pattern), it reconstructs the original 3D light field - a hologram.
