SpuriousLogic writes to tell us that University of Arizona researchers claim to have broken a barrier in holographic technology by creating an updatable, three-dimensional display with memory. While the existing model is only able to update once every couple of minutes, and isn't particularly suited for 3d images, it is certainly a step in the right direction. "Peyghambarian is also optimistic that the technology could reach the market within five to ten years. He said progress towards a final product should be made much more quickly now that a rewriting method had been found. However, it is fair to say not everyone is as positive about this prospect as Peyghambarian. Lecturer in Electronic Engineering at Bangor University in Wales, Dr Justin Lawrence, told CNN small steps were always being made on technology like 3D holograms, but, he couldn't see it being ready for the market in the next ten years."
