Introducing 'Desktop 3D Hologram Printer' that allows you to easily print real 3D hologram photos at home
The 'Desktop 3D Hologram Printer ', the world's first desktop-sized 3D hologram printer that can print a '3D hologram image' that looks three-dimensional when tilted at various angles on a special film with laser light, is now available. did.
3D Hologram Printer
The retail version of the Desktop 3D Hologram Printer looks like this. The main body size is 21.5 inches (about 55 cm) long x 20 inches (about 51 cm) wide x 11 inches (about 28 cm) high, and the main body weight will be about 13.2 kg.
The Desktop 3D Hologram Printer was developed by Liti Holo, founded by Paul Christie, a researcher at the Massachusetts Institute of Technology (MIT) Media Lab.
LitiHolo's Desktop 3D Hologram Printer creates holograms by irradiating a special hologram film with an interference pattern from two laser beams. Then, a 3D image is formed by the light that hits the pattern on the film and the diffracted light. LitiHolo states that the Desktop 3D Hologram Printer's 3D holographic photographs are 'real 3D holographic photographs' that are different from pseudo-images such as Pepper's Ghost, which uses optical illusions.
The following movie shows how the prototype of Desktop 3D Hologram Printer is actually printed. The laser is a 600-650nm red laser with an output of 20mW.

You can see what a 3D hologram photo printed by LitiHolo's Desktop 3D Hologram Printer looks like in one shot by watching the following movie.

The model is Buzz Lightyear from the anime movie ' Toy Story'. Seen from the front, it looks like this ...
If you turn to the left, you can see Buzz's face from the left.
Even if you turn it to the right, you can see that the right side of the face is also reflected and it is three-dimensional.
If you look at the 3D hologram photo illuminated by a typical LED desk light from the front and left side, you can see that the plate on which the 3D hologram photo is printed has no depth and is thin.
The specifications of 3D hologram photos that can be printed with the Desktop 3D Hologram Printer are as follows.
-The hologram is a reflective hologram and is visible under white light.
-The size of Hogel (pixels in hologram photographs) is 1 mm x 1 mm.
-The maximum photo size is 4 inches (about 10 cm) x 5 inches (about 13 cm).
・ You can see 3D only in the horizontal direction, and the viewing angle is about 45 degrees.
・ It is possible to prepare 23 patterns of appearance per Hogel.
Originally, 3D holographic photo printers exist only in companies and research facilities. LitiHolo has developed a special developing film plate to commercialize the Desktop 3D Hologram Printer for home use. This film plate does not require post-printing processing or development with chemicals, and is developed at the same time as it is exposed by laser irradiation.
Also, in order to create a hologram, it is necessary to load a set of fluoroscopic images showing how it looks in 3D into dedicated software. However, it is also possible to automatically extract the necessary perspective image from the movie shot by a specific procedure. In addition, it seems that you can prepare an image set by shooting what was rendered with 3D software with a virtual camera.
Desktop 3D Hologram Printer is looking for investment for commercialization on Kickstarter, a crowdfunding site. The target amount is 30,000 dollars (about 3.2 million yen), but at the time of writing the article, we have already collected about 118,000 dollars (about 1,280,000 yen).
