所谓集成就是把电路中的所有元件同时制作在单片材料上。

This integration is achieved by the simultaneous fabrication, on a single piece of material, of all components of a circuit.

这种设计方法不仅对于单片轴向梯度折射率透镜，而且对于同时包括均匀介质元件的光学系统也是很方便的。

The use of the method is not limited to simple lenses with gradient indices. It can also be used conveniently in the design of systems having homogeneous-medium elements.
