A team of scientists led by Professor Ramesh Raskar at MIT, have developed a camera which can take pictures around corners. The camera fires bursts of ultra-short high-intensity femto laser which last for one quadrillionth of a second (that's 0.000000000000001 seconds). The light then bounces from a surface like floor & strike the object hidden around the corner. The camera then captures the light particles returning back from the hidden object after striking from the same surface. The image is then constructed using complex alogrithms using a computer.
