MIT’s $500 Kinect-like camera works in snow, rain, gloom of night

Remember that camera that takes 1 trillion exposures per second? Well, the illustrious folks at MIT have outdone themselves (again) by developing a camera that accomplishes all that and more, for just $500. Similar to the recently released Xbox One Kinect, this three-dimensional "nano-camera" is based on "Time Flight Technology." That means an object's whereabouts are calculated by measuring the time it takes light to reflect off its surface and return to the sensor. But, thanks to some fancy math, the nano-cam can capture translucent and moving objects in 3D, using a new encoding method. In the past, the results of the process (which has been dubbed "nanophotography") could only be achieved with a $500,000 "femto-camera." With such a dramatically lower price tag, it could be a solution to one of the many hurdles facing self-driving vehicles: the ability to tell the difference between a puddle and a cat in the pouring rain. And, even though it functions like a Kinect, don't expect it to be standard issue with an Xbox Two (or One II, or whatever Microsoft decides to call it).

‘Twins’ Light Beam is Key to Fast Signals


The demand for fast signals has gone through the roof. If current trends continue pretty soon mankind will be up to its neck in fiber optics with online traffic causing logjams along these relay...
    


Researchers create hollow fiber optic cable, almost reach the speed of light

Researchers create hollow fiber optic cable, almost reach the speed of light

Fiber optic cables are usually made of glass or plastic but those materials actually slow down the transmission of light ever so slightly. Researchers at the University of Southampton in the UK have created a hollow fiber optic cable filled with air that's 1000 times faster than current cables. Since light propagates in air at 99.7 percent of the speed of light in a vacuum, this new hollow fiber optic cable is able to reach data speeds of 10 terabytes (!) per second. Now that's fast. While the idea isn't new, it's previously been hampered by signal degradation when light travels around corners. This new hollow fiber optic cable reduces data loss to a manageable 3.5dB/km, making it suitable for use in supercomputer and data center applications. Isn't science wonderful?

The Theory uses tiny MicroVision projector to concoct even tinier police chase (video)

the-theory-microvision-projector-police-chase-film

Looking like the ghost of Hot Wheels fantasies past, a new video short has beamed out of the minds at The Theory -- a production team that just happens to have a MicroVision pico projector. Called "Speed of Light", the mixed media film was made by projecting shots onto walls, floors and objects like laptops and then filming it with "no CGI trickery" added later, according to the team. Featuring a miniature Ford GT chased by a police car, helicopters, missiles and explosions, the pursuit was filmed with a Canon 5D MkII and HD MiniCam. To see if the little crook gets away with it, peel out to the video after the break.
