摘要：
A first cylindrical lens and a first linear sensor are constructed on the X axis, a second cylindrical lens and a second linear sensor are constructed on the Y axis, the X and Y axes are orthogonal, and the image width of a beam spot formed by each of the first and second cylindrical lenses is larger than each pixel of the corresponding first and second linear sensors.
