Submission + - A New Angle on Imaging (ieee.org)

Dog-Cow writes: "All cameras capture the intensity of light as it strikes their imaging chips. Color filters provide a second set of data, sorting the rays into different wavelengths. But new devices—including one produced commercially and others still in the lab—are starting to capture a third piece of information: angle. This allows cameras to go beyond focusing on a single plane to measuring images at many different depths of a scene at once. Cameras that capture both intensity and angle will allow for refocusing already-snapped pictures, lensless cameras, and the creation of 3-D images with a single camera, according to researchers in several competing groups."

Some people have a great ambition: to build something that will last, at least until they've finished building it.
