Engineers at Stanford University and the University of California San Diego have developed a camera that generates four-dimensional images and can capture 138 degrees of information. The new camera—the first-ever single-lens, wide field of view, light field camera—could generate information-rich...

Using IR laser ablation coupled with vacuum capture, a system of fingermark sampling has been developed that could be used for traditional fingerprint analysis and also to capture, filter and analyze biomolecules and trace substances such as DNA or explosives....

The inner workings of the human brain have always been a subject of great interest. Unfortunately, it is fairly difficult to view brain structures or intricate tissues due to the fact that the skull is not transparent by design. The...

The stiffness or elasticity of a cell can reveal much about whether the cell is healthy or diseased. Cancer cells, for instance, are known to be softer than normal, while asthma-affected cells can be rather stiff. Determining the mechanical properties...

Australian scientists have developed a polymer coating that can test for bladder cancer more simply and much cheaper than current invasive techniques. Professor Krasi Vasilev, from the University of South Australia’s Future Industries Institute, told Plastics News his team was...

Researchers have designed an optical lens that exhibits two properties that so far have not been demonstrated together: self-focusing and an optical effect called the Talbot effect that creates repeating patterns of light. The researchers showed that the combination of...

High-speed optical circuits and sensors generally require strict control over light polarization to minimize loss and cross-talk in photonic devices such as waveguides. An A*STAR team now predicts that noise resulting from imperfect polarizations can be eliminated using microstructures known...

Scientists have developed new 2D nanostructured surfaces that reflect light in such a way that they appear three-dimensional, conveying both shade and shadows. The surfaces can already be used for anti-counterfeiting purposes and could also have future applications in TV...

Brown University researchers have developed a new method of manipulating the polarization of light at terahertz frequencies. The technique uses stacks of carefully spaced metal plates to make a polarizing beamsplitter, a device that splits a beam of light by...

It’s hard to get an X-ray image of low-density material like tissue between bones because X-rays just pass right through like sunlight through a window. But what if you need to see the area that isn’t bone? Sandia National Laboratories...
