Biomimetic Imaging at last!

For hundreds of years, optical devices like telescopes and microscopes have relied on solid lenses that slide up and down to magnify and to focus. To tune how much light is received, conventional devices use mechanical contraptions like the blades that form the adjustable aperture in cameras.  Engineers from the Univ. of Freiburg in Germany have built a novel type of imaging system inspired by the elegance and relative mechanical simplicity of the human eye.
