| 英文摘要 | In laser engraving apparatus for engraving a gray-scale image on a plastic ID-card, the laser is a modulatable optically pumped semiconductor laser. Focusing optics focus a beam from the laser into a focal spot about 10 micrometers in diameter. The ID-card is mounted on a turntable which is rotated such that the focal spot sweeps over the ID card. The turntable is translated in a direction transverse to the rotation direction and the laser is modulated such that the engraved gray-scale image is formed by a matrix of parallel black lines of various length and spacing. |
