A novel microscopic imaging technique, developed by Brown University engineers to capture 3D images using quantum entanglement, may finally solve the problem of phase wrapping.

Undergraduate students Moe (Yameng) Zhang and Wenyu Liu presented their work at the recent Conference on Lasers and Electro-Optics. They worked on an independent project under the supervision of senior research associate Petr Moroshkin and Professor Jimmy Xu.

A one-pixel camera for recording holographic movies https://lifeboat.com/blog/2025/05/a-one-pixel-camera-for-recording-holographic-movies https://lifeboat.com/blog/2025/05/a-one-pixel-camera-for-recording-holographic-movies#respond Thu, 22 May 2025 10:26:20 +0000 https://lifeboat.com/blog/2025/05/a-one-pixel-camera-for-recording-holographic-movies

A new camera setup can record three-dimensional movies with a single pixel. Moreover, the technique can obtain images outside the visible spectrum and even through tissues. The Kobe University development thus opens the door to holographic video microscopy.

Holograms are not only used as fun-to-look-at safety stickers on , or banknotes; they have scientific applications in sensors and in microscopy as well. Traditionally, holograms require a laser for recording, but more recently, techniques that can record holograms with or light emanating from a sample have been developed.

There are two main techniques that can achieve this: one is called “FINCH” and uses a 2D image sensor that is fast enough to record movies, but is limited to visible light and an unobstructed view, while the other is called “OSH,” which uses a one-pixel sensor and can record through scattering media and with light outside the visual spectrum, but can only practically record images of motionless objects.

You’ve probably seen a movie in which a character pulls up a hologram display that they can poke, prod, and manipulate as easily as you could mess with a real object sitting on a desk in front of you.

The idea is so ubiquitous in science fiction that it’s become nearly synonymous with the word “hologram.” In almost every news story written about hologram technology and how far it has come, at some point, a disclaimer has to be made explaining that ‘it’s not quite Tony Stark tech, but it’s still cool!’

Researchers have succeeded, for the first time, in displaying three-dimensional graphics in mid-air that can be manipulated with the hands. The team includes Doctor Elodie Bouzbib, from Public University of Navarra (UPNA), together with Iosune Sarasate, Unai Fernández, Manuel López-Amo, Iván Fernández, Iñigo Ezcurdia and Asier Marzo (the latter two, members of the Institute of Smart Cities).

“What we see in films and call holograms are typically volumetric displays,” says Bouzbib, the first author of the work. “These are graphics that appear in mid-air and can be viewed from various angles without the need for wearing virtual reality glasses. They are called true-3D graphics.

They are particularly interesting as they allow for the ‘come-and-interact’ paradigm, meaning that the users simply approach a device and start using it.
