Seeing through walls



Light passing through walls, that's sounds like a science fiction right. Actually it does. Well if you count on lasers, it can. And also X-ray can see through suitcases and all in airports but this time Jochem Aulbach from FOM institute of Atomic and Molecular physics in Amsterdam, Germany has developed a new technology that allows scrambled light to pass through ultra thin layers of paint.

When light is passed through opaque materials it gets muddled and lost in space time continum. Aulbach and his crew used a Spatial light Modulator(SMT) to control a 64 femtosecond long laser pulse that's passed through a thin layer of paint. The light remains only long enough for machines to see and is recorded and send to a computer for calibration. With this new technology it might be possible to blast away the cancerous cells without damaging the surrounding healthy tissues.
