As I pointed out. Sometimes it's the reporter who doesn't really understand the science & sometimes it's the scientist making false claims. But the claim is that it's been achieved-nobody who knows what they're talking about denies that it can, theoretically, be done.

You mean like an interference pattern? Which is what creates a hologram? Sorry, that's also satire because you inadvertently explained how it works-while trying to explain why it wouldn't work.
So once it passes thru the interference pattern we're no longer talking about a beam. And you're correct that current technology requires bulky equipment-that's one of the reasons why it's still in the labs. (And they don't really need rotating mirrors, but it's easier. If I remember correctly, what they need is two beams interfering with each other in order to produce the interference pattern we see as an image. (And it won't be a single pixel unless that's the image you want to produce. The basic nature of a hologram, as an interference pattern in light, requires that they 'produce' the entire image rather than a portion of it.) The mirrors & prisms are currently used to 'split' a single beam into two synchronized beams, then bring them back together to produce that interference pattern.
Will it ever be miniaturized enough to fit into a pocket-sized device? I don't know. It's certain that it theoretically can be, but that theoretical device requires all sorts of technology that is also still theory. It's possible the human race will die out before this proves true. It's possible some other technology will be developed to do essentially the same thing before this proves true. And it's possible that there won't ever be enough 'need' for this that people will continue to develop it. But it's also definitely true that it is possible. Whether or not that possibility will ever become reality is something else.
