What remain to be improved are the effect of the general noise in grating-making on the output quality and the imbalance ofdiffraction order intensity.
光栅制作时引入的综合噪音对输出质量的影响及各衍射级能量的不均衡问题尚待进一步改进。

The relative intensityof Fresnel single-silt diffraction can be expressed approximately by means of two simpler integrals.
