Optical devices

3D without the glasses

Nature volume 495, pages 316–317 (2013)Cite this article

Subjects

A glasses-free three-dimensional display technology has been invented that may be an exciting alternative to current solutions for mobile devices. It makes use of an optical effect known to school physics students. See Letter p.348

We are all familiar with the glasses needed to watch three-dimensional (3D) movies. But glasses are inappropriate for many possible uses of a 3D display. There are a range of technologies that can achieve 3D without the glasses. On page 348 of this issue, Fattal et al.1 describe a new form of illumination device that could help to achieve it for mobile devices.
