Photography measures what quantity of light of the various color spectra hits the photographic film. We should know that light is also a wave, and the phase can be identified as well.
Within the wave cycle, the phase determines the specific point in the repeating cycle and connects to a depth of information. Recording the aspect of light distributed by an object can quickly recover its full 3D pattern. That cannot be collected with a standard photograph. It’s the base of optical holography, Twich is familiarized by fancy holograms like in Star Wars and other sci-fi.
But it has one problem. The geographical resolution of the hologram or photo is narrow compared to the wavelength of light. It can be about one µm or under 0.001 mm. That is suitable for macroscopic objects, but it begins to fail when it reduces to the realm of nanotechnology.
Now researchers have established a way to identify how light behaves on a linear scale, behind wavelength limitations from Fabrizio Carbone’s lab at EPFL. They used the most extraordinary photographic media: openly proliferate electrons. They also used their high-speed electron microscope. The system can encrypt quantum information in a holographic light form captured in a nano format, and the phenomenon emerges due to an unusual condition of electron and light interaction.
To divide the electron-reference and electron-imaging beams in preferable energy area, the scientists used the quantum form of electron-light communication. Now it’s possible to use light pulses to encode facts onto the electron wave activity, which can be graphed using high-speed communication electron microscopy.
This new method can prepare us with two significant advantages. First, information encoded in the light itself makes it a powerful tool for imaging electromagnetic fields with attosecond and nanometer rigor in time and area. Second, the system can be used in quantum computing applications to shape the quantum house of complimentary electrons.
The new technique also has the most spatial resolution if you compare it to substitutes behind quantum computations. It could absolutely change the way we imagine and consider light in everyday life.
