This system encodes information as holograms within a high-power laser beam. As the beam passes through a nonlinear medium, the information becomes completely scrambled, making it impossible to ...

EPFL student and lead author Maria Isabel Alvarez-Castaño explains that another unique aspect of the holographic approach is that the hologram beams can be made ‘self-healing’, meaning they can spread ...

Additionally, by controlling the individual beam powers as the print progressed, up to eleven grey-scale values could be generated, allowing variable material properties to be realized. Holograms ...

These can subsequently be read back by shining the original reference beam onto the same portion at the exact angle that was originally used to create the hologram. The diffractive properties of ...

The type of hologram that is created in the video is the simplest type, called a transmission hologram, as it requires a laser light to illuminate the holographic film from behind to recreate the ...

Bill Belichick's 24-year-old girlfriend Jordon Hudson goes topless in sizzling Instagram snap Jordon Hudson has surely grown used to making waves Brad Pitt, 61, looks ageless as he admits risking ...

The data are read out by diffracting the reference beam off the recorded hologram (see Fig. B1b). The data page is regenerated and captured by an array detector, where each pixel of the detector ...
