See Only What You Should: UCLA’s Game-Changing Imaging Tech

Diffractive deep neural networks, specifically the pyramid-structured optical networks developed by UCLA’s team, represent a significant leap in optical technology.

This pyramid design optimizes image fidelity and magnification in a specific direction, restricting it in the opposite. Validated by terahertz illumination tests, these networks prove effective in magnifying and demagnifying images with high accuracy, opening doors to applications in telecommunications, privacy, and defense.

UCLA researchers introduced an innovative design for diffractive deep neural networks (D²NNs). This new architecture, termed Pyramid-D²NN (P-D²NN), achieves unidirectional image magnification and demagnification, significantly reducing the number of diffractive features required. These results have broad applications in optical communications, surveillance, and photonic device isolation.
