Imaging array proves adept at capturing details as small as a fingerprint. A unique camera that can capture a detailed micron-resolution image from a distance uses a laser and techniques that borrow from holography, microscopy and “Matrix”-style bullet time. A prototype built and tested by engineers at Rice and Northwestern universities reads a spot illuminated by a laser and captures the “speckle” pattern with a camera sensor...
