MIT Laser Sends Sound Messages
Transmitting Sound By Light to Your Selected Recipient
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 message is sent by sweeping the laser at the speed of sound to a specific distance and targeted recipient. Sweeping the laser creates loud audio. The scientists have also modulated it for higher resolution.
Safe and Being Further Developed
The MIT scientists say this is the first laser system that is fully safe for the eyes and skins to localize an audible signal for a specific person in any setting. They are now working on increasing the reach beyond the current 8 feet and exploring commercial applications. For more news stories on important innovations, go to amazon.com/author/ekane
