The three-dimensional image of Princess Leia broadcasting her distress message is part of popular culture. Even those who have not seen the films of the saga, easily associate the holograms with Star Wars. If anything, holographic technology has a promising path ahead. The arrival of 5G will allow heavier images to be transmitted through networks. In this way, it will be easier for these 3D images to be adopted as a standard in communication between people.

Video calls, so common since the pandemic took over our routines, could be made using a 3D hologram. It’s not just the speed of the network that will influence our ability to deal with holograms. Also the low latency. These two aspects, of paramount importance in 5G, will allow images to be transmitted properly and not be unbalanced or suffer interruptions.

The origin of holography

The differences between holography and photography are obvious. The second captures a two-dimensional snapshot, while the first offers three-dimensional or multidimensional information. When the viewer moves they will see different angles of the projection and this will make sense at all times.

This result is reached through decades of research. One of the pioneers in this field was Dennis Gabor, who studied Mechanical Engineering at the Polytechnic University of Budapest and the University of Berlin. There he began to work in one of the physics laboratories of the Siemens company. Following Hitler’s rise to power, he was forced to leave Germany because of his Jewish origins. And it was in 1947, in the United Kingdom, when he happened upon a new method of forming images on a circular transparent slide. He called that technique holography, for ‘holos’ (everything, in Greek). Its discovery went unnoticed at first but years later it gained international recognition. So much so that in 1971, Gabor received the Nobel Prize in Physics.

How holograms work

It can be said that a hologram is a record of the interference that occurs between two beams of light when the light from one of the beams reflects off the object. This registration is carried out with a laser beam on a photosensitive film. From there, it is possible to generate a three-dimensional projection of the image.

When it comes to image projection, it’s really just a matter of having the right receiving device. “Holography works the same as live streaming, but changing the final screen for a holographic device”, point out from the technical department, specialized in holography. “Although it is always necessary to follow the specific technical parameters of lighting and recording as per techguff.com.”

5G as a boost for holography

In the field of holographic images, 5G will be a boost. The graphics are very heavy, so the high speeds offered by the new generation of networks are adequate. But also its low latency, thus avoiding interruptions. Otherwise, the projections may suffer cuts and decompensation.

“Currently enough powerful network connections are needed to avoid delays in full HD broadcasts,” they point out from 3DH. “ With the arrival of 5G we hope to avoid these delays and to be able to broadcast in 4k without problems . It will help us a lot in the retransmission of holographic images ”.

There have been several pilots who have made video calls with holograms via 5G networks. And this is one of the applications being considered as a driver of the new connectivity. It is based on augmented reality. Two people could sit quietly chatting, each with the other’s hologram.

It seems like a thing of the future, but in 2017 the first international video call was already made. It was made between Seoul and New Jersey. In South Korea, KT Telecom, one of the participants in the project, pointed out that this type of communication would be available with the new 5G. The idea is to provide a greater sense of reality. From the flat image of video conferencing, it would move to a three-dimensional one, which would capture much more detail, such as body language.

The following year another milestone took place in the field of holography. Mischa Dohler, a professor of wireless communications at King’s College London and a music composer, demonstrated the capabilities of the technology at a concert. It was a live event, where he acted as a pianist on stage while his daughter sang through a hologram. The holography showed the girl a few meters from the piano, singing to the rhythm of her melody. The two were 1,000 kilometers apart, but the latency was minimal, so the result was impressive.

It’s just two glimpses of what holograms can do. From 3DH they list, as the main applications of technology, ” communications, events, exhibitions, fairs, shops, and businesses “. Although they point out that they are currently developing “new holographic applications for education, in schools, and the cultural sphere, for museums.”

Meetings via holographic telepresence

With current technology, it is possible to generate video calls with holograms. This is what the project offers a telepresence system that shows an assistant remotely through volumetric video. For this, augmented reality techniques will be used. Participants in this holographic meeting will have to wear HoloLens 2 type glasses.

The remote assistant will be staged in a 3D augmented reality figure. The idea is that it can be observed from all angles. A factor that will be useful for training in different areas, such as rehabilitation techniques or medical interventions. But objects can also be displayed in 3D, which will be useful when examining prototypes in industry, for example.

It will be necessary to deploy a volumetric capture room. This will feature multiple depth cameras, such as Intel’s RealSense. What they will do is capture the 3D figure of a person in real-time. From there, the images will be generated using Evercoast software. To send them, considerable bandwidth will be needed and here 5G comes into play. Thanks to edge computing processing, multidimensional images can be served to meeting attendees.

Video calls with a 3D hologram on mobile

The next step is to take the holograms to much more everyday terrain. This is what some initiatives that have put smartphones in the spotlight are looking for. From these devices, they have been able to generate holographic images, although not always with good resolution.

One of the methods used is simply an optical game to channel the light, with a simple pyramid projector. Of course, it is not the most advanced, but today almost all holograms generated with smartphones need some type of projector. Although some have tried to create them using only miniaturized technology, integrated into the smartphone, such as HoloFlex. For the moment, the results have to improve.

Get ready to dive into a world of renewable possibilities as we shed light on all things solar. Join us at https://www.sumitrapower.com/ and let’s embark on an enlightening journey together!

One crucial component of any residential solar installation is the inverter, which converts the DC power generated by solar panels into usable AC power for your home. While traditional string inverters have been the go-to choice for many years, there’s a newer technology that’s gaining momentum – micro inverters. In this blog post, we’ll explore what micro inverters are, how they work, and the numerous advantages they offer for residential solar installations. So let’s dive right in and discover why micro inverters are revolutionizing the way we harness solar power!

How Micro Inverters Work

Micro inverters are an essential component in residential solar installations, working silently behind the scenes to convert the direct current (DC) generated by each solar panel into usable alternating current (AC) that can power your home. But how exactly do these small devices work their magic?

Unlike traditional string inverters which connect multiple panels together, micro inverters are installed directly beneath each individual solar panel. This means that each panel operates independently, optimizing energy production even if one or more panels are shaded or experiencing different levels of sunlight.

When sunlight hits a solar panel, it generates DC electricity. The micro inverter then steps in and converts this DC electricity into AC electricity suitable for household appliances and the electric grid. By doing this conversion at the individual panel level, micro inverters eliminate any power loss resulting from mismatched panels within a string.

Furthermore, micro inverters allow for real-time monitoring and optimization of each individual panel’s performance. With integrated communication capabilities, you can easily track your system’s output and identify any potential issues such as faulty panels or shading problems.

This modular approach also simplifies installation and maintenance processes. In case of a malfunctioning or damaged module, only that particular micro inverter needs to be replaced without affecting the functioning of other panels.

By harnessing the benefits of advanced technology and providing greater flexibility and efficiency than traditional string inverters, micro inverters play a crucial role in maximizing energy generation for residential solar installations while ensuring optimal performance under varying conditions.

Benefits of Using Micro Inverters in Residential Solar Installations

Benefits of Using Micro Inverters in Residential Solar Installations

Micro inverters have revolutionized the way solar power is generated and utilized in residential settings. Unlike traditional string inverters, which convert DC electricity from multiple solar panels into AC electricity for use in the home, micro inverters operate on a panel-by-panel basis.

One of the major benefits of using micro inverters is increased energy production. With traditional string inverters, if one panel is shaded or underperforming, it can impact the output of the entire system. However, with micro inverters, each solar panel operates independently, optimizing energy production even when some panels are partially shaded or experiencing other issues.

Another advantage of microinverters is enhanced safety. Traditional systems utilize high-voltage DC wiring that can be dangerous to handle and maintain. In contrast, microinverters employ low-voltage AC wiring which poses a lower risk of electrical shock. This makes installation and maintenance safer for homeowners and professionals alike.

Additionally, microinverters offer greater flexibility in system design and expansion. Since each panel functions independently with its own dedicated inverter unit, homeowners can easily add or remove panels as needed without impacting overall system performance.

Furthermore, monitoring capabilities are another significant benefit provided by microinverters. With integrated wireless communication technology, users can conveniently monitor their individual panel performance through web-based platforms or smartphone apps in real-time. This allows for proactive maintenance and troubleshooting as any issues arise promptly.

In conclusion (not concluding), incorporating microinverters into residential solar installations provides numerous advantages over traditional string invertors including improved energy efficiency, increased safety measures along with simplified maintenance procedures ensuring optimal performance throughout the lifespan of your solar power system

Maintenance and Upkeep

Maintenance and Upkeep

Like any other component of a solar system, micro inverters also require regular maintenance and upkeep to ensure their optimal performance. However, the good news is that maintaining micro inverters is relatively simple compared to traditional string inverters.

One advantage of using micro inverters in residential solar installations is that they are designed with individual monitoring capabilities for each panel. This means that if one panel or micro inverter experiences an issue or underperforms, it can be easily identified and addressed without affecting the entire system’s output. In contrast, with traditional string inverters, a single faulty panel can significantly impact the overall energy production of the entire array.

To maintain your micro inverter system effectively, it is recommended to keep an eye on the individual monitoring data regularly. Most manufacturers provide online portals or mobile apps that allow homeowners to access real-time information about their solar systems’ performance. By checking these platforms regularly, you can identify any anomalies or deviations from expected energy generation levels promptly.

In addition to monitoring data, occasional visual inspections are also beneficial. Check for any signs of physical damage such as cracks or loose connections on both the panels and micro inverters themselves. It is essential to clean the panels periodically as dirt and debris can reduce their efficiency over time.

Although maintenance requirements may vary depending on your specific installation and manufacturer guidelines, it is generally advised to have a professional inspection every few years. During this inspection, licensed technicians will assess the condition of your micro inverters and perform any necessary repairs or replacements.

By ensuring regular maintenance and upkeep of your micro inverter system, you can extend its lifespan while maximizing its energy production potential throughout its lifetime.

In conclusion,

Microinverters offer numerous advantages when used in residential solar installations. Their ability to optimize energy harvest at an individual panel level ensures maximum efficiency even under shading conditions. With improved safety features like rapid shutdown capabilities and easy expansion possibilities for future scalability needs, homeowners can have peace of mind while enjoying the benefits of solar energy.
