A gravitational lens is formed when light is bent by a massive object.
引力透镜现象就是光被巨大质量物体弯曲的现象。
If a large object passes in front of a more distant background star, it may act as a lens, bending and distorting the light of that star so that it may appear to brighten significantly.
如果一个体积足够大的星体从一个距离很远的恒星前面经过，那么会产生透镜效果，使那个恒星的光线产生弯曲或变形，这样就能很清楚的看到这个星体。
If the objective lens is closer to the compact disk than the focal length of the object lens then the cylindrical lens creates an elliptical image on the photodetector array.
如果物镜与光盘之间的距离短于物镜的焦距，柱面透镜就会使在光电探测器阵列上的成像变成椭圆影像。
