Surface acoustic waves can be used to steer laser beams, in ways that could lead to glasses-free ‘3D’ displays, according to the Charles Stark Draper Laboratory in Massachusetts. The proof-of-concept device has been made using techniques that could be scaled for production, according to Draper research engineer Gregg Favalora: “We can report the first demonstration, ...
