IMAGING

Graphene light-field camera

Nature Photonics volume 14, pages 134–136 (2020)Cite this article

Subjects

A new light-field imaging scheme, employing stacks of transparent graphene photodetectors, has been demonstrated, providing a path to greatly simplify the otherwise complex three-dimensional imaging.

Painters of the Renaissance struggled to depict true colours, light and the three-dimensional (3D) nature of the objects in their paintings. To depict true colours, they would often use expensive pigments, while to get the authentic light values, painters such as Vermeer are believed to have used camera obscura. Modern colour cameras have solved these problems and can now record 2D projections of a 3D object with accurate colour and light value. However, such 2D projections provide little or no information about the depth of objects within the scene. Painters and photographers have long been fascinated by the idea of realizing 3D images that not only depict colour and brightness, but also depth information.
