此方法减小了相位离散值引起的量子化噪音，它适用于制作一切球面和非球面的具有旋转轴对称的相息图。
The method reduces the noise caused by discrete phase on reconstructing imago. This method can apply to either spherical or aspherical kind of Kinoform with axial rotating symmetry.

至少有一个非球面透镜位于球面透镜和印刷版面之间，用于将激光聚焦或会聚到一个所需点上。
At least one aspherical lens is arranged between the spherical lens and the printing form, for focusing or converging the laser light onto a desired spot.
