Scientists have utilized holographic projections to achieve unprecedented resolution in a light-based 3D printing technique.

In holography, a hologram is created by capturing the interference pattern formed when a coherent light source, such as a laser, illuminates both the object of interest and a reference beam. This ...

The superposition of holograms obtained by the self-interference of each point light source constitutes the hologram of the entire object. Therefore, as the object area increases in the ...

Instead of storing digital information in the form of bumps in a reflective surface of the disk — as is the case with DVDs and CDs — holograms are recorded in the volume of interference ...

Here, a spinning disk is written and read by a focused beam and data is represented by isolated "micro-holograms." These are tiny (several microns cubed) volumes of Bragg retroreflectors written by ...

In short, precisely arranged lasers reflect off objects to encode interference patterns on a recording medium. When light hits the finished hologram, nanometer-scale variations in these patterns ...

Memory may take the form of interference patterns that resemble laser-produced holograms Experiments with monkeys have identified the brain areas involved in the recall of various learned tasks.

This deep learning-based approach provides an entirely new framework to conduct holographic imaging by rapidly eliminating twin-image and self-interference ... using only one hologram, requiring ...

HoloTile involves superimposing multiple holograms of a desired projection pattern, and eliminates random light interference called speckle noise that would otherwise create grainy images. Although ...
