Develop super-thin optical structure with higher quality than dedicated lens

"The traditional lenses in camera lenses can be scaled into ultra-thin chips but still ensure excellent optical properties." That's what the Harvard University study said after the successful development of a method of transmitting light through ultra-thin nano-titanium (TiO) films suspended over a flat quartz plate, promising to create a revolution not only in photography but also many other optical tools in the future.

The entire flat structure above is only 2mm thin and follows the Harvard team led by Professor Capasso, this is the smallest size they can create with the available equipment, but this method will already creating a big revolution in the field of optics, allowing printing of lens structures like a chip. And needless to say, that success not only allows the creation of ultra-thin cameras for mobile devices but also enhances the accuracy of scientific devices.

We have heard so much about how cameras work before, that before going to the light sensor, light must go through the lens system and, in general, from the 19th century until now, the lens cast tradition is still the only way to do this. Therefore, perhaps this breakthrough discovery by Harvard University could create a revolution in the future of photography. Briefly on the new system, light rays will enter a winning structure like millions of hair strands, then focus themselves after passing through the quartz surface and the other problem is to use an algorithm to optimally distribute the path of light like a traditional lens.

In fact, the team says that this structure not only avoids distortions and aberrations that often appear on traditional lenses, but can also guarantee "better image quality than technology imaging lenses." Art is highly appreciated now ". In the experiment, the researchers measured and determined that the focusing point is 30 times more sharp than the highest quality equivalent lenses today. And more interestingly, the study also revealed that "flat structures can turn a phone camera or contact lens into a microscope".

While production costs are now the biggest barrier to preventing such technologies from being commercialized, this approach seems much more promising. The reason is that the Titanium Oxide mentioned above is simply a silver coating and due to its ultra-thin nature, we can completely mass produce by casting in the factory with any Any size according to needs. If successful, this technology will be a revolution for the camera industry, while supporting the development of virtual reality technology, which has a very intimate relationship with glass.
