Artificial eye automatically stretches to simultaneously focus and correct astigmatism and image shift. Inspired by the human eye, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed an adaptive metalens, that is essentially a flat, electronically controlled artificial eye. The adaptive metalens simultaneously controls for three of the
Researchers have been pushing the capabilities of materials by carefully designing precise structures that exhibit abnormal properties that can control acoustic or optical waves. However, these metamaterials are constructed in fixed geometries, meaning their unique abilities are always fixed. Now, new 3-D printed metamaterial developed by a team led by USC Viterbi researchers can be
Researchers have created the first “metalens” that can focus the entire visible spectrum of light onto a single point in high resolution. The breakthrough brings metalenses one step closer towards replacing bulky camera lenses with much smaller chips. The new technology could lead to high-resolution camera lenses that are thinner than a human hair. Instead
