MIT camera uses lasers to capture images from around corners | VIDEO

It fires these lasers at a wall, which bounces them into a room. The beams then reflect off objects and people before re-emerging and striking a detector. The detector takes measurements every few picoseconds, or trillionths of a second.

The camera does this several times, bouncing light off several different spots on the wall to cover several angles.

The system then compares the time at which each light beam returns to the detector (and their angle), to piece together a picture of the room’s geometry. It’s a bit like ultrasound, or the way Microsoft’s Kinect uses a bunch of infrared dots to determine 3D shapes.

Researchers at the Massachusetts Institute of Technology have built a camera that can see around corners, by bouncing bursts of laser light off doors or walls.

The system works like a periscope. But instead of mirrors, it uses ordinary walls, doors or floors; instead of light, the camera is equipped with a femtosecond laser that emits bursts of light so short that their duration is measured in

quadrillionths of a second.

Using Light, Intel Confirms Data Will Be Sent Wayyy Faster in the Near Future

Intel announced a prototype technology today capable of moving data at 50 Gbps, comparable to sending an entire HD movie in one second – foreshadowing faster, longer data connections that could be revolutionary for consumers and data center users.

The prototype represents an important advance in Intel’s research into silicon photonics – using lasers instead of electrons to send data – which the company has been working on for years. Intel hopes to scale up the technology until it reaches speeds close to a terabit per second – fast enough to transfer a copy of the entire contents of a typical laptop in one second, the company said.

Data transmission speeds over wire-based connections are limited by bandwidth and distance. Intel turned to silicon-based photonic devices in order to transcend these physical limitations and continue to make more powerful chips.

With the new process, electrical signals are translated into light at different-colored wavelengths, which are combined and travel down a single fiber. Then the light is separated back into wavelengths and converted back to electrons. The speeds are so high that processors, memory and other computer components will no longer need to be placed inches from each other, implying vastly different computer designs in the future, the company said.
