Researchers from the University of Ottawa and Imperial College London have developed a new ‘quantum-inspired’ holography technique that uses lasers to render a 3D image.
Led by Dr Benjamin Sussman, adjunct professor of physics in the Faculty of Science at the Univeristy of Ottawa, the researchers aimed to record and reconstruct extremely faint light beams.
The University of Ottawa says the team’s work could enhance 3D scene reconstruction and be used in applications such as autonomous vehicles and augmented reality, as well as in fields such as astronomy, nanotechnology, and quantum computing.
"The quantum-inspired holography technique introduced by our team presents two significant advantages over traditional holography methods,” says Sussman. “Firstly, it showcases remarkable resilience to mechanical instabilities such as vibrations during the hologram recording process. Unlike conventional holography, which necessitates short exposure times due to susceptibility to vibrations, this new technique enables researchers to record holograms for extended durations, ensuring superior precision. And secondly, our new technique can be employed to record holograms of self-luminous or remote objects.”
