A team of scientists from Australia and China managed to create a hologram 1, 000 times thinner than a human hair. The researchers hope the invention will pave the way for the introduction of 3D holography into consumer electronics, including smartphones, computers, and televisions.
According to the head of research, Professor Min Gu, ordinary computer-synthesized holograms are too large for electronic devices, but the ultra-thin hologram created by scientists overcomes this barrier.
A simple and fast laser recording system is responsible for the formation of a nanohologram, the design of which is suitable for industrial production and widespread use in medical diagnostics, education, data storage and other fields.
The desired effect was achieved using a topological insulating material with a low refractive index. It is a thin film that acts like a resonator that increases the phase shifts for a holographic image.
According to research co-author Dr. Zen Gui Yue, the next phase will develop a thin film for an LCD screen that powers a 3D holographic display. In addition, scientists intend to create a series of flexible elastic thin films for other electronic devices.
