摩尔偏析测量术通过测量探针光束经过不均匀介质后光线的偏折来估算介质的折射率。
Moire deflection measurement can be used to calculate refractive index by measuring deflection of probe beam passing through mediums.
但原始激光束光强的不均匀分布影响了陶瓷改性的一致性，不利于激光烧结工艺的准确控制，严重者还会损坏陶瓷。
However, the intensity of original laser beam spot can not be distributed uniformly, which is bad for controlling the laser sintering condition. And the ceramics may be destroyed.
分析发现激光束通过硬边光阑后会出现大量的强度尖峰，引起近场的强度分布不均匀。
It is found that lots of intensity spikes emerge and the near field intensities are non-uniformity when the pulses pass through the aperture.
