MIT Laser Sends Sound Messages
Transmitting Sound By Light to Your Selected Recipient Source: MIT Breakthrough Laser System from MIT This is breakthrough technology innovation. A new laser system that can send an audio signal directly to a person's ear, at a distance away, without any one else detecting it. It has just been developed by scientists at MIT Lincoln Labs. Alexander Graham Bell's Research Basis Incredibly, this technological breakthrough has its roots in research performed by Alexander Graham Bell a century ago. The new system relies on the photoacoustic effect, in which material forms sound waves by absorbing light. 'Whisper' Laser Tech The "Whisper" laser tech sends sound messages to a specific recipient whom the sender is targeting. It can beam tone, music and speech from a distance. It is literally transmitting sound by light. The light is highly intense lasers and the recovery material receiving the sound message is water in the air. The sound...
