比如 10 米乘 10 米的网格，取每个交叉点的值（共有 100 组）就形成一个光栅数据集。

Taking a 10-meter-by-10-meter grid and making one observation for each intersection (100 observations) would constitute a raster dataset.

通过在每个像素上(构成画面的点)采用极小的镜片或衍射光栅，从线条发出的光被引导进入正确的眼睛。

The light from the lines is directed to the appropriate eye using either tiny lenses or diffraction gratings over each pixel (the dots of which the picture is composed).

通过液晶光栅编码可以直接获得被测物体形貌特征点信息，提高了测量速度和效率。

It can obtain the feature point information of measured object directly and improve the measuring efficiency.
