Smartphones nowadays are already frequently used as cameras and the number of megapixels or other photo specs have become vital for customers. But there’s a way to make smartphone cameras even better.
Scientists from Harvard University invented flat meta-lenses. This technology increases the photo quality significantly. As you may know, traditional lenses are made of glass or other translucent materials. Such lenses have a certain curve radius, so the smartphone makers have to install bigger sensor which gives a smartphone more weight and thickness. The meta-lenses from Harvard are composed of titanium oxide pillars. The pillars are usually super-thin and these lenses can reflect the light in one focal point.
New innovative lenses are much more compact and lightweight than regular ones. By installing meta-lenses on most mobile devices (smartphones, tablets, etc.), the quality of photography will increase drastically. The lenses also affect thickness – all mobile devices will become thinner. Plus, all chromatic aberrations will be corrected.
A few months ago, meta-lenses have been successfully tested in monochrome systems. The scientists are already working with the blue-green spectrum and we may soon see the final version. If this technology eventually comes out, it will definitely be a revolution in smartphone making.
