摘要

Thousands of times per second a point of light turns on and off, moving side to side, top to bottom. It is a rhythm that ticks around the world, illuminating living rooms and office desks in the process. However, the cathode-ray TVs and monitors that metronomically fire electron guns at viewers — who are shielded only by thin sheets of glass — are rapidly being replaced by flat-screen technologies. Yet as the creation of images using scanning electron beams fades into history, a new form of technology is emerging that builds up pictures by scanning with light.
