Caltech camera chip yields superfine 3-D resolution

摘要

Imagine you need to have an almost exact copy of an object. Now imagine that you can just pull put your smartphone, take a snapshot with its integrated 3-D imager, send it to your 3-D printer, and within minutes you have reproduced a replica accurate to within microns of the original object. This feat may soon be possible because of a new, tiny high-resolution 3-D imager developed in the laboratory of Ali Hajimiri, Professor of Electrical Engineering at Caltech. This design is described in the February 2015 issue of Optics Express.
