Imaging Array Captures Details as Small as a Fingerprint from a Distance

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. Engineers from Rice and Northwestern Universities built the prototype device that compares interference patterns between speckled images by reading a spot illuminated by a laser, which captures the pattern with a camera sensor. The raw data from the camera is fed to a computer program that interprets it and constructs a high-resolution image.
