Camera chip provides superfine 3-D resolution: New imaging technology fits on a tiny chip and, from a distance, can form a high-resolution 3-dimensional image of an object on the scale of micrometers

"The small size and high quality of this new chip-based imager will result in significant cost reductions, which will enable thousands new of uses for such systems by incorporating them into personal devices such as smartphones,"
