Hologramas Com Scanner

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.
