Decoding multiple frames from a single, scattered exposure

Engineers at Duke University have developed a way to extract a sequence of images from light scattered through a mostly opaque material—or even off a wall—from one long photographic exposure. The technique has applications ...

ESA technology making L.A. Metro a safer ride

Thousands of daily passengers on the Los Angeles Metro will ride more securely with the deployment of cutting-edge ESA-patented screening technology to detect concealed weapons or explosives.

Researchers push the boundaries of optical microscopy

The field of optical microscopy research has developed rapidly in recent years. Thanks to the invention of a technique called super-resolution fluorescence microscopy, it has recently become possible to view even the smaller ...

Extremely small and fast: Laser ignites hot plasma

When light pulses from an extremely powerful laser system are fired onto material samples, the electric field of the light rips the electrons off the atomic nuclei. For fractions of a second, a plasma is created. The electrons ...

Fiber optic sensor measures tiny magnetic fields

Researchers have developed a light-based technique for measuring very weak magnetic fields, such as those produced when neurons fire in the brain. The inexpensive and compact sensors could offer an alternative to the magnetic ...
