The light-plate that is shot by semiconductor laser comes to a certain Angle to throw overlap joint, which brings a single vein of light, and CCD camcorder shoots and sends it to the computer.

半导体激光器发出的激光经过柱透镜形成一出射光片。它与母材成一定角度投射到接头上，光片与搭接接头会成一单光纹，而母材垂直上方的CCD摄像机拍摄折线光纹，同步送计算机处理。

This metal plate is exposed to light and creates an image which is then transferred to paper.

这种金属板在曝光后可以产生能被转移到纸上的图像。

Ice crystals should be plate shaped. They float in the air close to the ground reflecting light back downwards.

冰晶需呈片状，它们悬浮近在地面的空中，将光线向下反射。

Most photomasks are created by etching away a thin film of light-blocking chrome from the surface of a quartz plate.

FORBES: Trick of the Light

The third objective, efficient design, involved sandwiching the nanostructured bismuth telluride between two copper plates and then enclosing the upper plate (the one coated with the light-absorbing oxides) and the bismuth telluride in a vacuum.
