Pyramid Power: Technology Similar to Earth’s Oldest Known Structure Leads to Game Changer in Optical Communication – The Debrief

A potentially revolutionary new technology that could dramatically improve the optical communications, surveillance, and isolation of photographic equipment has something in common with the most fascinating architectural design of the ancient world: pyramid.

UCLA researchers have developed a new revolutionary design for deep neural networks, or D2NNs, that they say improves image processing and large-scale decomposition. Dubbed Pyramid D2NNs, the new architecture lives up to its name by introducing a pyramid-shaped network that provides high-fidelity imaging while minimizing refractive errors, all by connecting its parts on the same side to enlarge and enlarge the image.

What are Diffractive Deep Neural Networks?

D2NNs are built with multiple layers of deep learning-enhanced transmission, allowing them to be completely computationally efficient using optics.

In their latest research, the UCLA team, led by Professor Aydogan Ozcan, worked with a pyramid-shaped diffractive optical network, a design that allowed the team to achieve different images freely. weak.

The result is a design that helps ensure a high image quality, but only in one way. On the other hand, the significant restriction of images occurs in the opposite direction, conditions that are important for use in applications where imaging is performed in one direction (i.e., imaging in one direction). different) as needed. Such factors include security and safety technology, mobile communications systems, and systems used to protect privacy.

The team was also able to demonstrate modularity and scalability for their proposed pyramid system by deploying several P-D2NN modules. This allowed them to reach even greater magnification points.

The Secret of the Pyramid

The pyramid structure has long fascinated the human mind, and there is no better example of this than the amazing pyramids of Giza.

In simple terms, a pyramid is a three-dimensional structure resulting from the construction of triangular faces that appear on a polygonal base. Each of the points of the three parts meet at the highest point or top.

This creates a unique structure where the weight is evenly distributed, which allowed ancient architects to rely on this design for the construction of some of the largest buildings ever built, for example most famous with the pyramids of Giza, still impressive monuments. today’s engineering standards, and which have proven their solidity by persisting for thousands of years. Because of their mysterious appearance, the pyramids have also contributed to many different ideas over the years, including the mysterious powers that the monuments of Giza may have or the claimed sciences (most of them pseudoscientific) based on the shape of the pyramid and the power it is said to possess. .

For the UCLA team, the pyramid structure provided real-life benefits in that the ascending structure allowed them to measure the components of the new D2NN in a way that corresponds to the direction of enlarging or reducing the image. In other words, the pyramid structure provides a kind of guide that can enlarge or reduce the image being asked about in a controlled manner. The result is that high fidelity images are able to convey progress over the internet, but only in the desired way.

During their research, the team also succeeded in validating the new P-D2NN system using terahertz (THz) light. Various 3D-printed parts were tested under continuous THz light, producing results that the team says are in close agreement with earlier numerical simulations.

Applications and Future Prospects

This system is suitable for a variety of applications, including technologies that provide optical separation for photonic devices and integrating transmitters and receivers for telecommunications. In the coming years, the new pyramid-shaped system could also benefit security and even surveillance technology.

Overall, the P-D2NN class architecture represents a major advance in optical imaging technology, which its developers believe could help pave the way for a wide range of strategic and real-time applications. coming. Of course, they all depend on one of the most amazing and captivating ancient structures in human history.

The team’s findings were published in a journal Light: Science & Applications on July 31, 2024.
