Harvard Researchers Develop Extremely Thin Artificial Eye

Engineers at Harvard University have just created an extremely thin artificial eye they believe will revolutionise camera lens design. Today, researchers involved in this study are trying to incorporate these lenses into the cameras of tomorrow.

Called a "metalens," this new electronically-controlled lens was made according to the latest findings in the field of muscle technology. This technology allowed scientists to get rid of issues related to image shift and astigmatism that often contribute to unfocused images.

Study authors say this new metalens is able to focus on an object even faster than the human eye. Anyone can use these metalenses by changing the amount of voltage that flows into the lens. Amazingly, this new lens only measures 30 microns (or 0.03 millimeters) thick.

In addition to helping consumers take better photos, researchers hope this new metalens will improve scientific research in fields like astronomy and microbiology. Engineers are interested in putting their metalenses in hi-tech telescopes and microscopes to enhance scientific research. There's even talk that these metalenses could help people with certain visual abnormalities in the future.

Alan She, a grad student at Harvard's John A. Paulson School of Engineering and Applied Sciences, was the lead author of this study. A few other researchers involved in this study include Shuyan Zhang, Samuel Shian, and Federico Capasso, all of whom also attend the John A. Paulson.

Interested engineers can read more about this study in the latest edition of Science Advances. This study was published under the title: "Adaptive metalenses with simultaneous electrical control of focal length, astigmatism, and shift."
