Your eyes and brain don’t always agree with each other. Sometimes your brain fills gaps, ignores details, or assumes patterns that aren’t really there. That’s exactly why optical illusions feel so ...

Optical illusions are designed in such a manner that they serve more than an entertainment source. These puzzles are also ...

Optical illusions have always fascinated me because they reveal how easily our brains can be tricked by simple patterns, color, design, and even different shapes and 3D models. When I first looked at ...

Vision, microscopy, imaging, optical data projection and storage all depend on focusing of light. Dynamic focusing is conventionally achieved with mechanically reconfigurable lenses, spatial light ...

Only those with excellent observation skills can find the hidden koala among the pandas in this optical illusion image. Can ...

Image showing gold contacts where we bias each laser with DC current. Light is out-coupled from the racetracks using the directional-coupler waveguides along the straight section of either racetrack.

The patterns of light hold tremendous promise for a large encoding alphabet in optical communications, but progress is hindered by their susceptibility to distortion, such as in atmospheric turbulence ...
