Ready for the close up
New scrambing technique could lead to sharper images.
A new imaging method could allow for lenses that allow sharper detail of all elements in a close up. The team, from Princeton University in the US, say that the technology could lead to more powerful microscopes and opticial devices.
All optical devices, including the human eye, are subject to the limitations of the amount of light that they can collect and record. Many light rays, however, do not make it through. The new technique takes advantage of substances called nonlinear optical materials. These mix light and allow information on rays to pass along that otherwise would be lost. The resulting image would be rich in detail but also distorted. This information, however can be unscrambled and a high detail undistorted image reproduced.

Commenting on the development, lead researcher Jason Fleischer - assistant professor of electrical engineering at Princeton - said: "It allows you to take a closer look at an object without narrowing your field of view."
