3D Printed Lenses Replicate Eagle Eye Vision

Eagles have famously sharp vision, and a group of scientists at the University of Stuttgart have managed to replicate that eagle-eye vision using a 3D printer to print four tiny plastic lenses of varying focal lengths directly onto a single image-sensing microchip. The lenses with longer focal lengths capture high detail over a narrow field of view, while the lenses with shorter focal lengths capture lower detail over a wider field of view. The entire four-lens camera measures less than 300 micrometers squared - about the width of three human hairs, and could potentially be used for tiny drones, sensors on driverless cars or even devices that could look inside the human body.
