Now, a new way to make self-assembling compound eye structures

A researcher in the United States has devised a technique to make tiny compound eye structures that self assemble, which he believes may revolutionise micro-imaging by providing an accurate field of view of up to 90 degrees, just like flies have.

London, January 15 : A researcher in the United States has devised a technique to make tiny compound eye structures that self assemble, which he believes may revolutionise micro-imaging by providing an accurate field of view of up to 90 degrees, just like flies have.

Compound eyes are formed from a large number of honeycomb-like tubes that guide light towards a sensor.

Luke Lee, a bioengineer at the University of California, Berkeley, says that he first creates a honeycomb pattern of micro-lenses by placing droplets of a polymer onto a sheet and allowing them to form lens shapes under their own surface tension.

The sheet of hexagonal lenses is later deformed into a dome shape, he says.

The whole process eventually leads to a tiny compound eye structure that Lee believes provide an accurate fly's-eye view of the world for the first time, reports New Scientist magazine.
