    This is incredible! It’s very hard to believe due to how far this team, and the university has went with volumetric holograms. I’m sadly still a little confused on how this work, but I got great deal of understanding on this project. I got an idea about holograms, and got curious about how this works. Thank you for sharing this amazing research with us.

    Photophoresis is cool. I'd imagine you could also achieve similar results with acoustic trapping. The latter technique has the advantage of being able to levitate larger objects and several at once, one within each acoustic node in the standing wave.

    Since these are real particles, the algorithm to create a 3D hologram and make all the particles move in complete synchronization would be massively complex! The software would be more mind-blowing than laser projection onto a trapped particle.

    • @kennichdendenn
      @kennichdendenn 3 года назад +2

      I would not think so - essentially, we already have solved that problem for 3d-printing for example. Using multiple particles could be made easier if every particle just has its "pocket" to fill. Then its just dividing the image into cubes.

    • @graalcloud
      @graalcloud 2 года назад

      In software code actually you would be surprised. The object is to make the code simple, not complex. So an algorithm to make stuff like this happen is probably more about sequentialization of the process and may not even be more than 100 lines of code.

  • @greensky01

    I had always though about this type of technology. Knowing well that a particle would have been used to reflect light. Have you though about setting a base filled with nanoscopic particle what are able to be magnetized. This would allow the particles to be moved around within the magnetic field (our your laser particle manipulator) and illuminating the particle.
    I can visualize the first "true" holographic set to be something akin to the old tube TV sets. It would probable have a heavy base where all the components would go. The center would have the laser emitters affixed to angle microscopic mirrors for the said particles. Each particle would have its own microscopic guidance system. It would function in the same manner as the old cathode ray tube TV sets where the electrons were guided in the X and Y coordinate system. However, due to the complexity a base for the X and Y coordinates would be used, and one back wall for the additional Z coordinate along with any other color and image stabilizers.

      I just read the paper, and apparently it's actually fairly robust. It's not going to stand up to wind, but you should be able to breathe on it or make hand gestures without messing it up. (It *will* be disrupted if you actually touch the particle and knock it out of the trap, but the particle can achieve pretty high velocities and accelerations; it should definitely be feasible to track your hand and maneuver the particle around it.)

For instance, what you see in popular imagination movies (like Princess Leia or avatar tree or iron man arm) are volumetric images.

    • @BYU
      @BYU  6 лет назад +41

      They don't rely on ambient dust. They introduce particles, usually composed of black liquor (cellulose) or tungsten, and trap them in the laser beam and then the laser light is manipulated to steer the particle and create the image. In our video for demonstration purposes, particles are introduced with a spoon; the researcher sweeps the particle-filled spoon through the laser until a particle falls into the trap (and then laser light bounces off the particle as it moves, creating the image). They are automating and refining the process of course but that's what you see in our video demo. More information can be found in Nature: www.nature.com/articles/nature25176

    • @Nerdule
      @Nerdule 6 лет назад +2

      No - it's based on a different principle. It's more like those mist displays that project onto a wall of fog; but instead of just dumping a bunch of particles into the air, they capture single particles inside a specially-shaped laser beam at an invisible wavelength and project colors onto that single particle. By moving the laser beam around and adjusting its focus, they move the particle around in 3D space, and so can project different colors at different points in space, building up full 3-dimensional shapes.
      Basically, it's just like any projector that needs a screen to project onto - but with this clever trapped-particle trick, they can have a special single-point screen that only exists at the specific location they need to project onto at any particular moment.

    • @Nerdule
      @Nerdule 6 лет назад

      No, you don't need any special kind of thing to project the image into. The thing that keeps the particles trapped is actually a single, specially-shaped hollow laser beam that keeps the particle trapped in the center of the beam at a particular position; You need a special *projector* to project this kind of beam, but it's not that big of a deal. The colors are then produced by illuminating the particle with regular red, green, and blue lasers coming out of the same projector.

      >"Will this work outside in the wind, or with a fan on?"
      From the paper:
      "Particles are sensitive to airflow. Under good trapping conditions, trapped particles are robust to low levels of airflow, including airflow generated by human breathing and hand gestures (estimated airflow upper bound of one litre per second). However, it is unlikely that the display would function outdoors without an enclosure unless particles were much more strongly confined or steps were taken to refresh trapped particles regularly."
      So, probably not, although if you replaced the particles quicker than the wind could knock them out of the trapping beams, it might work.

      Impractical due to complexity.

So many of these will need to be made and if you wish to retrieve the particles you need a similar system with lasers guiding them so might as well use their method.

      "Hologram" is actually a scientific term, dating back to 1949, that's has a specific meaning that's different than the usual science-fiction usage to mean any kind of futuristic 3-D volumetric display. A hologram is a photographic recording of a *light field* - instead of a usual photograph, which just captures the total intensity and color of all the light rays passing through each point in a region, a hologram captures the full detail of all the light rays passing through a region - amplitude, wavelength, *and* phase. So it doesn't just have a color for each pixel, like a regular photograph, but it has a color for each pixel *for each direction it's viewed from.* When you tilt a hologram and look at it from an angle, you'll see the object that was photographed from a different point of view, and it'll look 3D because each eye will be looking at it from a different direction and getting a different angle as a result.
      But it's not really a 3D thing at all - it appears fully 3D without needing any kind of special glasses or headsets or computer tracking, but it's still just being displayed on a flat surface. They are also extremely difficult to display electronically; holographs are generally recorded and displayed on special photographic film.
      Really, *none* of those displays - plasma-dot displays, this trapped-particle display, augmented reality displays - are truly "holograms"; the people marketing the augmented-reality displays are just using the popular sci-fi definition of a virtual 3-D object, and the scientists in this video are talking about the scientific definition.

    Invented a long time ago in a laboratory far far away... Congratulations you have reinvented traveling through hyperspace to build technology that was already invented years ago.
    All you had to do was look up the patent number.
