Every now and then, somebody comes up with a radically new way to improve technology and do something different. One such example is the Flexible Sheet Camera that researchers at the Laboratory for Unconventional Electronics at Columbia University have developed. Rather than a little handheld box with a single lens and some sort of zoom optics, this super-thin concept camera lets you adjust the field of view by simply bending it:
Light field technology that’s currently available, like the Lytro Illum or Raytrix’ industrial light field cameras, is largely based on microlens arrays which allow the flat imaging sensor to infer the direction of light rays in addition to their colour and intensity. While Raytrix has managed to ramp up spatial resolution to 25% of the actual sensor resolution by way of a customised, heterogeneous microlens array, effective resolution is still a limitation of today’s light field cameras.
Now, researchers at the Nanoelectronics and Nanophotonics Lab, University of Michigan, have announced working on a different approach that would allow capturing complete light fields at full sensor resolution. Rather than microlenses in front of a standard imaging sensor, the team around Zhaohui Zhong are developing a new sensor consisting of several transparent light detectors based on graphene, a material consisting of a single layer of carbon atoms.

Light field imaging has captured the mind of many technology enthusiasts and imaging pioneers, and there have been rumours of light field cameras in future iPhones or Android smartphones.
Now a new patent has surfaced that shows Apple is still interested in light field cameras. The twist is, the proposed “plenoptic” (a.k.a. light field) camera system is intended to aid robots in the manufacturing process. Continue reading
Earlier this week, Lytro announced a new product which takes the company into a new direction: The Lytro Immerge is a futuristic-looking sphere with five rings of light field cameras and sensors to capture the entire light field volume of a scene. The resulting video will be compatible with major virtual reality platforms and headsets such as the Oculus Rift, and allow viewers to look around anywhere from the Immerge’s fixed position, providing an immersive, 360 degree live-action experience.
