Lasers have previously been able to produce optical illusions, however have required a dust/cloud medium in order to do so
The Vuzix M300 AR headset is one of a variety of products targeting industrial applications
Andy Extance finds that although augmented reality products talk about holograms more than they use them, holographic technology still has huge potential
Physicists at the Australian National University have developed a miniature device that creates what they claim to be the highest efficiency infrared holograms demonstrated to date

As microscopes become ever more powerful, a growing band of businesses are racing to make the latest technologies more accessible and more affordable, reports Rebecca Pool
Illustration of a three-dimensional crystal with various types of confining centres. (a) Crystal with four confining centres, each trapping waves (yellow) in all three dimensions simultaneously. (b) Crystal with a linear confining centre where waves can propagate in one dimension, analogous to an optical fibre. (c) Crystal with a planar confining centre where waves can propagate in two dimensions, analogous to a 2D electron gas. (Image: Vos et al.)
