The diffractive properties of the three-dimensional interference pattern, namely the hologram, cause the reading beam to be diffracted, producing a similarly patterned beam corresponding to the ...

Close-up of the wavefront pattern recorded on the holographic film ... the videos on [3Blue1Brown]’s channel. The type of hologram that is created in the video is the simplest type, called ...

Forming a high-quality image from a single hologram or diffraction pattern has never been achieved for reasons relating to the optical physics. An alternative approach is therefore employed that ...

It is a hologram projector made with a thin plastic ... Grab the free instructions with a traceable template. The printable PDF pattern shows two different sizes. The smaller shape is best for ...

Transmitting optical information through highly distorting media has long been a challenge. Atmospheric turbulence, fog, and underwater environments distort light signals, making communication ...

By combining AI with holographic encryption, scientists have developed an ultra-secure data protection system. Their method ...

Digital currencies, communication channels, and sensitive data could be protected from cybercriminals using holograms, scientists propose.

Researchers developed a new optical system that uses holograms to encode information, creating a level of encryption that traditional methods cannot penetrate.
