Turn Your SmartPhone Into A 3D Hologram
Pyramidal holographic’s have become popular fast, with crowdfunding projects offering you ways to get into the game for just hundreds of dollars, but here is a way to put together your own small-scale version effectively for free.
The Science – Turn Your SmartPhone Into A 3D Hologram
Holography is the science and practice of making holograms. Typically, a hologram is a photographic recording of a light field, rather than of an image formed by a lens, and it is used to display a fully three-dimensional image of the holograph subject, which is seen without the aid of special glasses or other intermediate optics.
The hologram itself is not an image and it is usually unintelligible when viewed under diffuse ambient light. It is an encoding of the light field as an interference pattern of seemingly random variations in the opacity, density, or surface profile of the photographic medium.
When suitably lit, the interference pattern diffracts the light into a reproduction of the original light field and the objects that were in it appear to still be there, exhibiting visual depth cues such as parallax and perspective that change realistically with any change in the relative position of the observer.
Required tools – Turn Your SmartPhone Into A 3D Hologram
A smartphone, compact disc case, graph paper, pen, scissors, knife, tape or superglue.
Basically, you cut a partial pyramid from the clear material, fasten it together, set it on your phone, and load up a video that turns those surfaces into four-way reflectors simulating the visual experience of objects moving in midair.
Make this with the help of this and enjoy it in dark light. You can make it bigger sizes too. any doubts please comment.
