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 ...

This method utilizes coherent light sources, such as lasers, to create holograms—interference patterns that contain rich information about the phase and amplitude of light scattered by particles.

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 ...

A normal hologram is a recording of an interference pattern of light scattered from the object and so-called reference beam, and it replays a static image with all the characteristics of light ...

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 ...

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 ...

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 ...
