Electronic violin turns laser signals into music - tech - 22 March 2013 - New Scientist

THE sound of a violin bow across strings can be exquisite. But bowing well is hard to master. Now that smooth grace is encapsulated in a new kind of electronic instrument. Developed by Dylan Menzies at De Montfort University in Leicester, UK, the O-Bow uses optical sensors to track the movement of a real violin bow across a groove in a metal instrument.
