Audio: Laser microphone patented
Wired.com reports on a new type of microphone designed and patented by David Schwartz. The principle behind the design involves a laser beam measuring the vibrations of smoke particles in a tube as they are deflected by sound. There are two interesting video clips on the Wired.com page - one showing a demonstration of the second prototype and the other showing the components of the device.
