3. 以线阵CCD器件作为二维投影式光电瞄准传感器的感受部件，应用于对刀仪上。
The linear array CCD is used as a sensitive component in a two-dimensional projective photoelectric aim sensor, and the latter is used in the machine tool pre-set instrument.
A new effective data-fusion method is presented, which can eliminate the errors by using double sensors. First, the two sensors′ images are mapped into the light knife plane;
