Optics supported by artificial intelligence – neural holographic display
Scientists have developed a way to realistically reproduce reality in holograms. The display segment and AR technology could be revolutionized by new calibrations related to artificial intelligence. Opticians have decided to use AI to increase computing power without changing the specifications of the devices themselves. The results are very promising!
What defect do realistic holographic visualizations face today? Portal scitechdaily.com points out that they are unrealistic because they are shown as 2D renderings, and the human eye, in very large, organic terms, is accustomed to feeling depth in the image that surrounds it. 3D display technology based on laser light performs poorly in this aspect and suffers from so-called. specularity, as the nature of the laser light beam is unable to carry such an information payload to our retina. The problem is also the limited possibility to influence the appearance of the light wave, compared to e.g. to frames presented on LCD screens. This fact affects the rather poor resolution of such an image.
Science Advances has published a study that details describe mottle distortion in laser-based holographic displays, while discussing a technique to reduce it.
Gordon Wetzstein, associate professor of electrical engineering and head of the Stanford Computational Imaging Lab, and his team are working on something more revolutionary. They are engaged in solutions that will fill the void between simulation and reality. For now, their efforts are focused on creating displays that are more visually appealing and more pleasing to the eyes than the existing ones we use.
Physics is the key to success
The Scitech Daily article also points out another major drawback of holographic screens. It is Lack of possibility to reproduce real physical reality, what is related to m.in. with the delay registered by the eye between events and the shape of the image emitted by the source. The solution to this issue turns out to be artificial intelligence.
The role of artificial intelligence in the holographic process
Yifan Peng of the Stanford Computational Imaging Lab, as an optician and computer scientist proposed the implementation of a new technology – optical engine. This one is expected to drive modern holographic displays.
– It is only with the recent innovations in machine intelligence that we have gained access to powerful tools and opportunities to take advantage of advances in computer technology – said the scientist and co-author of the SIGGRAPH article.
An artificial intelligence-based engine is to implement machine learning in action similar to that known for our brains. The neural network is to mimic physics in real time and return the image in simultaneous looping, which will enhance the perception of realistic perception. Instant feedback is also information for the algorithm to correct and improve the image that encounters problems. This is how the calibration technique that works in real time and also reacts to the present image seen by our eyes.
Researchers, by testing such technology, have been able to create more realistic-looking visualizations with better colors, contrast and clarity than ever before. The technology has been identified a neural holographic display.
LED in holograms?
Camera looping optimization, coupled with an AI-inspired algorithm is to use LEDs and SLEDs. They are cheap, not too big and energy efficient. Classifying the technics, these bulbs can be classified as partially coherent light sources, as opposed to a coherent laser.
LED light improves display stability and avoids spots and mottling, but causes image blur and poor contrast. Hence the need for an algorithm specific to the physics of partially coherent light sources.
In a word of summary..
In general, delving into this technology may lead to reflections on the very way of seeing on different kinds of surfaces. It was described in a very interesting way by biecek.en in words: “Two shades of gray may or may not be distinguishable on a computer screen, and behave quite differently on a printed. In the case of computer screens we usually have much higher image contrast than in the case of print, but at the price of lower resolution. Most modern computer screens have a resolution in the range of 100-300 pixels per inch, laser printers have a print resolution of 600-2400 dots per inch.”
Interesting insights are also provided by interview with Małogrzata Osowiecka , itvip portal.pl referred to as “an expert on the brain, not the eyes,” in which she argued that pScreen brightness is harmful to the eyes, its curvature is required as well as that the number of hertz matters When it comes to image processing by the brain.
Holograms are also to be used in advertisements.
And also we can display our holographic images ourselves, using the application!
