University of Ottawa researchers have done some groundbreaking work on lenses, using nanotechnology to develop so-called metalenses that dramatically shrink down optics. But lenses still rely on space to produce images and the researchers have presented the concept of an optical “spaceplate” that propagates light for a distance much longer than the plate thickness, enabling future imaging systems to shrink even further. A spaceplate can be used to miniaturize all kinds of devices that manipulate light. “It’s a possibly revolutionary development in the field of optical science,” suggests photography and camera news site PetaPixel.

Wooptix approaches the problem of light-field image capture in an interesting way. Using a single camera lens, they capture the same image at multiple depth-of-field settings. They then assemble a 3D version of the captured image by identifying and grabbing the areas of each depth-of-field image that are in focus. The result is a clear, if slightly flat and layered, 3D image with some degree of parallax. The company’s tech could have multiple applications.

Apple has invested $700 million in producing synthetic sapphire, one of the hardest minerals on Earth, for the newest iPhone’s display screens. Sapphire is expensive to produce, but the material does not crack or scratch as easily as the glass currently used in iPhones. Apple and GT Advanced Technologies have opened a facility in Arizona to produce the new material. The facility’s ability to meet the demand will determine whether Apple rolls out an iPhone with a sapphire screen. Continue reading New iPhone May Feature Scratch-Resistant Sapphire Screen
