New improvements in design and manufacturing, including the use of additional aspherical lenses that can help counteract and correct the spherical aberration effect, mean today’s lens-building techniques come very close to producing uniformly sharp images. These lenses don’t have a perfectly spherical shape and can be very expensive and difficult to manufacture and design as lens makers essentially have to experiment and come up with a different aspherical shape for every application.
But that’s all going to change thanks to Rafael G. González-Acuña, a doctoral student at Mexico’s Tecnológico de Monterrey. After months of work, he managed to come up with a mind-melting equation that provides an analytical solution for counteracting spherical aberration, which had been previously formulated back in 1949 as the Wasserman-Wolf problem which stumped scientists for decades.
The First VR Headset came out in the 1960’s. Coined as the “Telesphere Mask” by inventor Morton Heilig. This device features stereoscopic (3-D) TV, wide vision and true stereo sound.
To the average person, that equation is probably just more confirmation that a career in physics and mathematics wasn’t for them. But for lens makers, it can provide an exact blueprint for designing a lens that completely eliminates any spherical aberration. It doesn’t matter the size of the lens, the material it’s made from, or what it will be used for, this equation will spit out the exact numbers needed to design it to be optically perfect.
The breakthrough won’t just appeal to picky photographers who’ve been plagued with minor focus issues no matter how much money they’ve invested in their gear. It promises to help improve scientific imaging as well in devices like telescopes and microscopes where improved sharpness could lead to other discoveries. But even the average consumer will benefit from González-Acuña’s work. It will allow companies to design and manufacture simpler lenses with fewer elements which cost considerably less while offering improved image quality in everything from smartphones to cheap point-and-shoot cameras.
Virtual Reality Travel Is Exploding. Who hasn’t wanted to walk down the streets of Venice, or escape to a tropical climate during a particularly rough winter? Some with a travel bug may find that they can partially feed their need for travel through virtual reality. In the fall of 2015, Marriott boasted about its ability to transport clients from London to Maui in 90 seconds, thanks to Oculus. The concept behind the campaign was that people would be inspired to travel, and book with a Marriott hotel. Since then, Hilton, Renaissance, and many others have followed suit.
