[ Watch the Video ] Lee Rannals for RedOrbit.com Researchers at MIT Media Lab are experimenting with giving a camera the ability to shoot pictures of objects that are not in its line-of-sight. The team wrote in the journal Nature Communications that they have developed a way to produce 3D images of a wooden figurine that was standing around the corner, in another model room. The system fires a "femtosecond laser" to send bursts of light to reflect off surfaces like walls in order...

Ultrafast lasers, lasers that emit light pulses that are as short as a few femtoseconds, have enabled a wide-range of fundamental science and applications over the past two decades. To highlight recent state-of-the-art developments in femtosecond lasers, the Optical Society (OSA) today published a series of papers as part of an upcoming special Focus Issue on Modular Ultrafast Lasers in its open-access journal Optics Express. The issue is organized and edited by Wilson Sibbett and Tom Brown...

"Lucky" combination of chemicals and laser pulses enables high-resolution, 3D patterning for futuristic optical materials Researchers in applied physics have cleared an important hurdle in the development of advanced materials, called metamaterials, that bend light in unusual ways. Working at a scale applicable to infrared light, the Harvard team has used extremely short and powerful laser pulses to create three-dimensional patterns of tiny silver dots within a material. Those suspended...

Researchers at Purdue University and the National Institute of Standards and Technology (NIST) have created a device small enough to fit on a computer chip that converts continuous laser light into numerous ultrashort pulses, a technology that might have applications in more advanced sensors, communications systems and laboratory instruments. "These pulses repeat at very high rates, corresponding to hundreds of billions of pulses per second," said Andrew Weiner, the Scifres Family...

A microlaser no bigger than a pinprick can accurately detect and count individual viruses, the particles that jumpstart cloud formation or those that contaminate the air we breathe. By Diana Lutz, Washington University in St. Louis A tiny doughnut-shaped laser is the latest marvel of silicon microminiaturization, but instead of manipulating bits it detects very small particles. Small particles play a big "” and largely unnoticed "” role in our everyday lives. Virus particles make...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'karpos', fruit.
