Laser comb system maps 3D surfaces remotely for manufacturing, forensics
NIST's 3D mapping system combines a form of laser detection and ranging (LADAR), which is sensitive enough to detect weak reflected light, with the ranging accuracy made possible by frequency combs, as previously demonstrated at NIST. The frequency comb, a tool for precisely measuring different frequencies of light, is used to continuously calibrate the laser in the imaging … [Read more...] about Laser comb system maps 3D surfaces remotely for manufacturing, forensics
