The result shows that the set-up noise can be restrained and the output SNR can be improved considerably by using broad band temporally partial coherent illumination.
结果表明，时间部分相干照明可以提高系统的输出信噪比，对系统的装置噪声有明显的抑制作用。
The concept of redundant illumination is introduced to ensure the coherent illumination of zone plate and reduce the effect of source instability and element vibration.
引入冗余照明的概念，以实现波带板的空间相干照明以及降低束线对光源不稳定性及元件振动的要求。
