We’ve all seen holograms in movies, and occasionally we see various versions of the effect in real life ... simple device to display a sort of hologram. His display relies on reflections.

The material's physical properties change in response to the pattern of light, and in this way information can be stored and retrieved at a later date. In much the same way that holographic images ...

Here is the demonstration of an incoherent *1 digital holography imaging system that enhances the light-utilization efficiency for high-quality image. Schematic of holographic imaging with LED ...

The display, dubbed SolidLight, goes beyond gimmicky holographic illusions that merely trick your eyes. Instead, it manipulates waves of light to converge, creating floating 3D images that look real.

The difference between holography and photography can be summarized perhaps most succinctly as the difference between recording the effect ... hologram, as it requires a laser light to illuminate ...
