Engineers make gigapixel holograms with a standard A4 scanner

Engineers make gigapixel holograms with a standard A4 scanner | Open Mind & Open Heart | Scoop.it

Standard scanners might be a little boring, collecting dust next to your printer rarely getting use now that everyone with a phone has a decent digital camera, and most workplaces allow a PDF signature rather than a handwritten one. Instead of allowing that scanner to sit around hogging a valuable power brick outlet, a team of Japanese engineers have turned it into a gigapixel holographic camera.

 

The reason why you don’t see holograms everywhere is not because we don’t know how to make them, but because the technology required to do so is currently quite expensive. A standard megapixel-based digital camera simply doesn’t have a high enough resolution to construct a hologram, so the photos have to run through an arduous post-production process that creates the hologram. However, cameras able to reach a gigapixel — which are expensive — are capable of creating the hologram with comparative ease. So, rather than figure out how to significantly decrease the cost of digital cameras capable of gigapixel resolution — or bite the bullet and pony up the cash for one — an engineering team from Japan’s Chiba University grabbed a standard digital scanner and combined it with a laser to create a holographic gigapixel camera.

 

The scanner used by the team — a regular 4800 dpi A4 paper scanner you could buy on the cheap from any office supply store — is capable of creating images with a resolution of over two gigapixels.

 

To generate a hologram from an object, a recording device and laser must be aligned with that object. The laser aims at the object, and the light (diffracted and not) is recorded by the scanner. That’s what the gigapixel resolution is for, as lower-res recording devices have trouble capturing the result. A standard scanner works similarly to this method, shining a light down the length of an object, with a line of CCDs scanning down the document and capturing the reflected light, but without the laser.

 

So far, the team used the rig to create 0.43-gigapixel holograms of tiny insects — a flea and an ant. Using a process the team called “band-limited double-step Fresnel refraction,” they were able to build the hologram in only 177 seconds, down from an original 350.

 

Though the team has managed to create gigapixel holograms using cheap equipment, the end result can’t be displayed on a standard monitor, because a 1920×1080 resolution isn’t high enough for the image. So, the team removed the need for expensive capture equipment, but still hasn’t broken through the expensive display barrier. At the moment, the team doesn’t seem to have a solution for this problem, but at least they’ve already solved the issue of creating a hologram with cheap equipment.

Chechnya: 200 years of background in four minutes

Alex Vielman's curator insight, November 16, 2015 1:20 PM

Chechnya may not be a country that one hears much about, but it is a country who has suffered the most from its powerful reigning neighboring countries. Chechnya has important oil deposits, as well as natural gas and others. Overall, Oil is a resource a lot of countries fight for and this is why Chechnya suffers from Russia. Russia wants to have territorial denomination of Chechnya. Russia throughout the years has fought and bombed over Chechnya for territory. It is similar to the situation in Africa, where small nations have been trying to break free from their regional superpowers and colonial rulers. The resulting anarchy in Chechnya strengthened Russian belief that the region should not become independent and undermine its territorial integrity. Overall, this is a problem all over the world and Chechnya still stands strong as an independent country. 

Adam Deneault's curator insight, December 14, 2015 1:40 PM

Clearly, Chechnya has a very violent past. It is nothing but a place of death and heavy conflict. You can even say it had a genocide going on, when the citizens of Chechnya was sent to Siberia to pretty much be killed off by the extreme cold. It is also important to understand that Chechnya wants to be it's own country. It is sad to hear about this country in such  negative way with all the fighting going on and the fact that the Boston Marathon bombers came from there... Why could we not hear of it in a better way better way? For example, they want to be a country of their own. 

Martin Kemp's curator insight, December 17, 2015 1:47 PM

first off i would like to say that i am pretty sure half of the world did not even know Chechnya existed until the marathon bombing happened. also this stuff is really important to know because it give you background and insight into what these people were thinking and how what goes on on the other side of the world can twist people in such a way that it effects us here at home.
