提出利用全息透镜阵列来实现多通道分数傅里叶变换技术。
In this paper, a technology of implementation of the multichannel fractional Fourier transform (FRT) is proposed using holographic lens array.
然后用原参考光照射处理后的全息图，同时再现出三个平面波，得到三光束干涉的六角形蜂窝状阵列式空间光强分布。
The hologram is illuminated with the original reference light, then spatial light intensity distribution of hexagonal honeycomb array produced by three ligh beams are obtained.
另外全息面具或者微透镜阵列，可用于集中的激光束的孔，以填补他们的金属。
Alternatively holographic mask or an array of micro lenses may be used to focus the laser beams to the vias to fill them with metal.
