The way of sound transmission by the laser directly in an ear is created


The laser bunch delivers the message directly in an ear of the person. It is almost impossible to intercept and decipher the coded laser message. Physicists from the Massachusetts Institute of Technology created essentially new way of sound transmission. He is brought by a laser beam directly in an ear of the person. Optics Letter reports about it. Experts created a way of enciphering and sound transmissions by means of the laser directly in an ear of "the specific recipient". By means of the special coding based on certain parameters, the transferred message cannot almost be intercepted and deciphered. The novelty is based on photoacoustic effect which allows to create a sound wave as a result of absorption by light material. The novelty can form the basis of creation of essentially new radio communication. So far the technology can transmit a sound on distance about two meters, but scientists work on expansion of its abilities. The day before the robot courier of Amazon began to deliver purchases.
