The technique could lead to the long-sought goal of producing holograms without bulky equipment.
The technology can create a miniaturized holographic image sensor for 3D digital holograms.
But previous polarization-sensing cameras were too bulky to be put into portable electronic devices.

The researchers developed a new jot down of photodiode by stacking special semiconductors.
Holographic displays offer unique capabilities, Wetzstein said.
Theres no true hologram outside of a lab that is ready, or cost-effective enough, for consumers.

“Were many years away from that technology becoming practical for everyday use.”
A few small companies are commercializing holographic displays,such as VividQwhich makes components for business use.
Wilkinson said the holographic devices are produced in low volume and therefore expensive.
But holograms may finally be having their moment.
Proto is building the infrastructure for hologram phone calls and meetings.
“Wed like to be the ones making the true holograms to run on the systems were creating.”
If they ever become mainstream, holographic displays could have a wide range of uses.
“That presence helps the brain understand things quicker than a flat display,” Nussbaum added.
And being able to beam this around the world can help in telehealth and so many other industries."
