Using lasers to create the displays of science fiction, inspired by Star Wars and Star Trek

[@craigwilliams9279]

1:08 I love that a science guy knows the difference between phasers and disruptors.

[@Hannes.Richter]

right xD so cool!

[@jasondeutschbein8102]

Came to the comments looking for this. Yes!

[@guruxara7994]

Maybe because he's an engineer...

[@smimoma5930]

Engineers and scientists are the biggest nerds

[@richardjohnson9543]

I'm becoming increasingly hopeful that holograms as we see them depicted in movies and TV shows will exist in my lifetime

[@anonymous2494]

Same, I am so excited for the future!

[@Hannes.Richter]

They will

[@Finn_553]

They will exist, and will look better

[@maniacalo2901]

Yeah they will, within 10 to 20 years if the need for it arises.

[@sqlevolicious]

Can't break physics, so it's definitely not possible and never will be. But something that is incased in a controlled space like locked particles with light or soundwaves is totally possible. The biggest hurdle being how do you scale this technology and how reliable could it become?

[@inceptional]

OK, it's clearly early days, but this is just cool. That tiny stick figure walking over the finger. lol

[@dungeonmaster1425]

Why this video has so few views? It's not fair. The whole world should know about it!

[@GeekMultiversal]

It is the reality of world society, most are only interested in what is happening in the lives of celebrities, players, musicians, singers, actors and socialities, who will never know, than to appreciate with that same enthusiasm, what will really be useful advances in science and technology. Disappointing the lack of interest of the public in a simple, but complex and revolutionary project, imagine that in the future, it could be useful in communication and even in health, in a Radiography in real time. I am already rooting for these students, that their project will progress a lot and even get attention from the newspapers.

[@BreatheMusic]

They will soon!

[@asleepawake3645]

All about the deplorable art of marketing, youtube recommendations has to reach more viewers. At least I'm glad this has now been reported by real journalists from The Guardian

[@laurenpinschannels]

200k is a lot of views

[@Blemishing]

It may be silly but this makes me excited. Y'all keep it up! Amazing. Gives me the chills.

[@huexley]

I was sure I would never see this in my lifetime! It's just amazing.

This could revolutionize stage productions, as well as augment or replace 2D displays.

Between this and SpaceX it's like all my childhood sci-fi fantasies are finally coming to life.

[@sqlevolicious]

[@sabscientists2528]

Does this mean that you have to wear laser glasses so that our eyes arent damaged? or are the lasers weak enough that no protection is really required? Im guessing the laser would be shining out of the volume as well

[@fest00n]

Yes, there is diverging laser 'splash' that the viewer should avoid. However, there is a lot of room for improvement in the power of the light used to trap and illuminate. Currently the lasers we use are 10's of milliWatts. I think a truly optimized trap could do the same job with an order of magnitude less power. It might also be possible to trap with infrared light which can have a much higher eye-safety threshold that the 405nm trap light we are currently using, for example.

[@danielsmalley6504]

This is a good question. The lasers are bright enough to be dangerous (tens of milliwatts) but I think there is a lot of room for reducing the required power to a safer level. Furthermore, we are also looking into trapping with infrared light which can have a much higher eye-safety threshold than the 405nm light we're using now. Having optically active particles is also an option. Yet another option would be to use intelligent illumination that will make sure the viewer is never staring down the optical axis.

[@BonJoviBeatlesLedZep]

@@danielsmalley6504 Intelligent Illumination sounds like a bit of a risk especially for someone fast into the beam. I hope the IR trapping works, that would be so cool

[@thoughtsofapeer]

I think a final product would be a glass cube with the lasers hidden in a bottom compartment of sorts. The glasses filter could then just be added to the glass cube avoiding the need for the users to wear glasses.

[@SeeNickView]

So, any frequency/energy level of light can damage our eyes, given a sufficient number of photons that actually hit our eyes. For blue light, ultra-violet, x-ray, gamma, etc., those photons/waves have such *high energy* that a _small number_ of them can damage the eye's molecules/DNA via chemical bond decomposition. For red light, infrared, micro, radio, etc., those photons/waves have too _low energy_ to do the above. However, your eye doesn't just dump the heat from those particles immediately and return to ambient temperature. As such, if a *large number* of, say, infrared photons hit your eye for a long enough time, the thermal energy stored in your eye can cause similar damages as those created from UV light. Hell, even in the visible spectrum, a high enough radiance/flux of photons for a long enough time can still damage your eye, albeit via "thermal/IR loading" and not from UV ionization. So, depending on kind of light emitted from these demonstrations, whether on the shorter side like UV or on the longer side like IR, it is still wise to wear some sort of protection. The thermal damage happens over a long time, so in reality if these viewings/showings are only for like 30 minutes or an hour, "thermal" glasses probably aren't as important as UV glasses. If the viewings/showings are for like hours at a a time, I'm thinking that thermal AND UV would be appropriate, just to be safe. Edit 1: photons, not protons Dx

[@dpsdps01]

The technology is amazing. Fantastic, groundbreaking technology. Can't wait where this goes in the future! And the guy with the round glasses has a fantastic fashion style.

[@AttakusZakus]

Finally, a reason to keep going and see how this awesome tech grows!

[@zombiedude245]

This is awesome ..I can’t wait to see this technology develop over time

[@arthurprado1271]

this is the coolest thing i've seen for a long time

[@ryanclarke2161]

Late 1940s we invented the transistor.....imagine where this stuff will be in 100 years.

[@angelmercy100]

Whaww this is a fantastic and promising technology ! But I don't understand how you "trap particle" and what particle is trapped, dust particle ? Does anyone knows ressources or articles where i can learn more about this topic ? Thx and congratulation for this awesome work !! Hello from France ;)

[@Error-xx2zs]

Are you joking?! this is absolutely game changing you can actually touch and interact with the images that are displayed. This will take our world to a new different era. To think that to achieve the third dimension is to just make a particle hang as it acts as the third dimension in the air and the beam just moves around the particle. This is insane! well done!

[@lualdiz]

This is like a 3D holographic Oscilloscope, i love it

[@kaou8790]

I need this in my cinematography, hope it gets more interesting for my future scripts!

[@Hannes.Richter]

This is the beginning of something BIG!!!

[@mikelastname9444]

I feel like using vision tracking and parallax effects is really missing the potential of what this technology is capable of. You're moving toward a space where images can be projected in such a way that they're visible to a large audience and take up actual space, which is great for immersive experiences where displayed objects are brought into the user's space, making them seem more tangible. But then you're taking a step back from that by attempting to recreate the experience of a flat screen in free space, so the viewer has to rely on illusions to get a 3d effect. The immersiveness of the experience is then lost by having the viewer remove themselves from their present environment to imagine a fictional environment, but at a degree of definition far lower than that provided by flat screens.

[@danielsmalley6504]

I agree that simulating virtual images removes some of the best parts of this technology; however, keep in mind that this technique will only be used for imagery that is too far away to generate directly or for imagery that is impossible to generate directly (like images that appear to be inside solid objects). It is just another tool in the storytelling toolbox, not unlike the painted backdrops in theatricals--they don't exist to replace the props, but instead to expand the perceived space.

[@manueletchegaray5437]

I suspect they have some strong technical limitations, thus went the path those limitations allowed them to go.

[@russwhiteman981]

@@danielsmalley6504 I have to agree with Mike, although I started from a slightly different place. Using parallax effects turns this into a purely single-user display. If that's going to be how it's used, then we might as well spend our efforts on improving headsets. This tech seems to promise that it will ALWAYS be far more expensive than headsets, while offering an equal experience.

[@SeeNickView]

Yeah I don't think you could create actually environments, like representations of buildings/walls or just objects, because at least some region(s) of the audience would have their vision impaired by the objects. A 2D projection works much better for movies/"images".

[@DanielSabelnikov1]

On the topic of interaction, what happens when you block lines of sight from lasers to image?

[@Skeptical_Numbat]

Amazing. This is just another of a myriad of new technologies which - in just a few years, to decades - will have a profound effect on our culture when it eventually matures...

[@romanmgelman]

Life imitates art, and you can’t convince me otherwise.

It's like magic becoming real.

[@theWarVet]

Holograms in it's infancy... just like the first CRT 100 years ago, it's seems like magic.

[@Orozco_PNW]

a very good analogy, this technology also relies on a similar concept of a single line scanning across a screen, except now it is levitating in three dimensions in the atmosphere! There are also examples of similar technology that use UV lasers to ionize voxels in the air, but I think it is dangerous and emits ozone? Anyway, I hope development of this accelerates!

[@jannpoppinga4680]

What is this particle? If it is air, why does it suddenly reflect light? If not, where does it come from? Also, do you see another possibility of increasing the volume (or rather total line length) of the display other than adding more and more lasers and scanners?

[@дединсайд-г6ж]

Amazing

[@tiagotiagot]

Since for the moment the size is still too small for full-scale stuff; how about using this tech for see-thru headmounted AR displays, or even VR, with a black backplate, and use the depth control to obtain multiple focal planes with the help of lenses?

[@jonnyreverb]

How are you addressing the convergence focal distance disagreement?

[@paddyharding8377]

What would happen if you touched the moving particle?

[@tomas12912]

I never belived that holograms will be sometimes real! Wow!

[@ShimrraShai]

It is very intriguing that the designers of the original Star Wars film gave a "scanning" appearance to the projection from R2-D2. Of course they were likely thinking of the old-style CRT monitors common at the time, but the funny part is by doing that they incidentally essentially almost "guessed" correctly exactly how you'd do this, i.e. with the same process but happening in free medium like air. I wonder what has become of this since. It seems still quite a long ways from the Star Wars one because obviously this huge mechanism does not fit into the small head of a child-sized robot ... but at least it shows the principle is solid and thus that it is possible to do at all, so the rest is as they say "just" a matter of engineering :D

[@someoneyoumightknow2795]

Just imagine hollywood studios of the future with that technology well settled :O

[@johnnemo4146]

He says that most of these images were done with long exposures. It would be interesting to know which ones were, and even more interesting, which ones weren't. I guess those that weren't, were those showing one single particle, one single luminous spot. So in order to create a 3D picture we can see with our naked eyes, the lasers should be able to sequentially move a lot of particles at a high frequency, or move a single one really, really fast (what are the speed limitations?), which becomes complicated (I guess), and more so for more complex images. What are the assessments about the ability to create 3D images that can be seen with the naked eye. What are the problems, and Is it feasible? Also, what are those "particles"? Are they something specially engineered?

[@reaper84]

Impressive!!!

[@JohnSmith-zf1lq]

Are the "phaser blasts" real time?

[@highwaltage]

is this light interference? the non visible laser being the beam that has the volume for the higher power to illuminate when they meet?

[@Zmef]

it's hologram is Tangible Holographic Plasma?

[@GhostEmblem]

can you use it to make a 3d printer?

[@ddegn]

I didn't know BYU had courses in black magic? This technology is so extreme it looks like magic to me. It will be interesting to see when/if this new display tech can be used in practical applications. Thanks for sharing the video.

Okay... I need these guys to come over here so I can use this technology to mess with my neighbors that I strongly dislike.

[@asleepawake3645]

So basically like the vector displays of old but instead of a static crt screetn n9w you're also dragging the display ( particle ) in 3d space

How do you trap the particle in the first place, and if you put your hand in front of it and move it away. Would it reset the whole thing?
