Holographic images now faster than ever.

Holographic images have been used to guarantee authenticity to original products, but for years researchers have been trying to get full holographic images for specialized fields like medical diagnosis. Earlier 3D vision was not stable enough to produce a vivid image and reproduce another one as quick as required, however the photorefractive polymer created by Savas Tay and colleagues at the University of Tucson, Arizona may help to change that as it removes some of the obstacles to producing them. Holographs are created by mixing reflected laser light with a second laser beam to lay down a static image – typically a lengthy, complicated and delicate process. Mr. Tay and colleagues describe their thin-film polymer that can have images “written” to it in minutes and can be wiped as quickly to take and display another image. The material has been shown to stay stable throughout hundreds of write and erase cycles. The ability to quickly refresh images in holographs could mean that surgeons use them as a guide during operations or as a better way for pharmaceutical researchers to study molecular interactions for new drugs during simulations.

The team has automated the process of capturing, writing and erasing images via a system that can take input from MRI, CAT scans, satellite or aerial photographs and microscopes. Working with hi-tech firm Nitto Denko the researchers have so far only made a screen measuring 10cm by 10cm.
