When the word hologram is heard, it is directly related to a projection made by very complicated and expensive electronic equipment. However, the action of creating holograms is not something so new, it is even studied as a tool of photography. Since it is very simple, learn how to make a professional homemade hologram projector.
Creating a hologram requires, in addition to an expensive holographic projector, the understanding and understanding of the visual phenomenon that allows the visualization. By understanding this you can make a professional homemade hologram projector and get amazing results.
However, there is also a slightly less complex option like creating a 3D hologram with your smartphone if the hypothetical scenario arises.
What is a hologram?
A hologram is in short a photographic phenomenon associated with the vision of images in three dimensions, the product of the use and management of light. This works by playing multiple opposing planes that they will generate the different faces of the projection in space.
Holography is precisely the study of three-dimensional effects in photography, because it is widely used to generate effects in the film industry.
Steps to make a professional homemade hologram projector
The first thing to do in making a homemade professional hologram projector is to download or produce the video to be displayed on the projector. This video should consist of an object placed four times in front of you. Showing the different faces of the element and also its synchronized movement in case you want to add.
On the Internet there are these types of videos for playback. But if you want to recreate your object, the most convenient thing is to produce it from the Adobe After Effects program.
Using 3D Warehouse with Google SketchUp you can create accurate three-dimensional images and other programs like Photoshop also allow you to create a 3D road pot map, just one of many examples.
There are also models for this where it will only be necessary to supplant the image on the screen with the desired object and it will already have the correct size for its holographic projection. Once you have the video, you should proceed to creating a professional homemade hologram projector.
Note that the dimensions may depend on the device to be reproduced, if it is a phone it will be small, but if you can use a monitor you can recreate a larger hologram. The principle is the same, what changes is the size of the projector to be produced.
On mobile devices
In the case of the mobile device , four trapezoids 1 cm wide on one side and 6 cm on the other must be made, plus 3,5 cm in height. These are drawn on a plastic or glass CD and then proceed to the cut and you get the four pieces of the projector.
The next thing is to cut it carefully, as in the case of glass it may splinter causing damage. In plastic, you have to be careful with cutting tools.
Once the four pieces have been cut and the edges cleaned, glue on the side corresponding to 3,5 cm, thus forming a truncated pyramid. It is advisable to clean the surface of the pieces well before paste them e use epoxy glue for this process.
Subsequently, a fifth piece will have to be made which will consist of a square of the same material of 6 cm on all sides. Next, this piece will be glued onto the 6 cm part of the piece made with the trapezoids, placing it as a cover.
The next thing would be to place the video on the mobile device and position the truncated pyramid at the top with the narrow part down, thus obtaining a holographic projection of the element reproduced on the mobile.
On a monitor
It is preferable to have a new generation monitor or a Smart TV, although there is also the possibility of converting an old TV into a Smart TV with Android.
The process is the same, but a projector must be manufactured to your TV's inch measurements and make sure that the angle is always 45 ° on all sides.
