Tiny Camera Captures Images without Lenses
Researchers at Cornell University have developed a tiny electronic camera that captures images without using lenses to focus the incoming light.
The planar Fourier capture array takes images from an array of angle-sensitive pixels. For example, the camera reconstructed an image of the Mona Lisa.
Researchers at Cornell University (U.S.A.) have developed a tiny electronic camera that captures images without using lenses to focus the incoming light. The imager, made through a standard semiconductor fabrication process, has no moving parts and is less than 1 square millimeter in size and about 10 µm thick (Opt. Lett. 36, 2949; doi: 10.1364/OL.36.002949).
