The new technology will make a revolutionary leap in the design and technical specifications of almost any optical device, including smartphones, cameras and telescopes.
Harvard School ResearchersEngineering and Applied Sciences John A. Paulson (SEAS) has created an innovative lens that resembles the human eye. The new lens is able to adjust focus in real time, which is ensured by the presence of elastomeric, artificial muscles. Traditional spherical lenses are deprived of such an opportunity. The lens also has unique capabilities, such as astigmatism correction and image shift. In violation of such functions of the eye, a person's vision deteriorates - he sees blurry, unfocused images.
Flat lens used by the newThe “artificial eye" is called metalinza and it uses tiny nano elements to focus the entire visible spectrum of light into a single point. In conventional lenses, several elements are used for this, which makes them so large.
Until now, only verysmall metal, but in the last experiment, scientists were able to get an “artificial eye” with a diameter of 1 centimeter. Such dimensions are necessary for practical use. So in the materialization chamber should completely overlap the sensor in order to avoid the effect of vignetting.
Development is in the testing phase and beforeindustrial production takes a long time to start. Nevertheless, the technology has a great future in which hardware integrated with mini-processors will be used in virtual reality devices in smartphones cameras and other optical devices.
