The new technique uses a 3D laser to ablate a curved surface, followed by etching in acid. This method can produce high-quality 3D concave lens arrays that can be used to make soft compound eyes.

A new method has been developed for fabricating 3D compound eyes. The technique uses a 3D laser to ablate a curved surface, followed by etching in acid. This method can produce high-quality 3D ...

The first working compound-eye-style camera can’t quite see like a dragonfly.Dragonfly eyes are made of tens of thousands of individual light sensors, says biologist Robert Olberg to the blogger ...

What am I looking at? These images show several views of the repeating units, called ommatidia (1), that make up the eye of a dragonfly. The colors you see in these images are the result of a process ...

A UC Berkeley engineer, entranced by the uncanny ability of insects like dragonflies and bumblebees to peer in all directions at once, has for the first time created microscopic versions of their ...

Their massive globular eyes should have been a clue. It turns out dragonflies have souped-up colour vision that’s better than anything ever seen in the animal world. We humans have what’s ...
