对阵列光栅压缩器远场方向图分布的数值分析表明，只需调整两个光栅的倾斜角度和两个光栅的相对位置距离，就可以实现光栅的对准。针对米级阵列光栅，通过简单的公式建立了对准公差判据。以尺寸为0.5 m的阵列光栅为例，角度和位置公差分别要求为0.25 µrad和λ/13。
A numerical analysis for far-field pattern distribution of an array grating compressor showed that alignment of segmental gratings can be achieved by adjusting only two tilted angles and the relative position distance of two segmental gratings. An alignment tolerance criterion was set up with a simple formula for an array grating with the size of meter order. For the example of an array grating with a size of 0.5 m, the angular and position tolerances are required to be 0.25 µrad and λ/13, respectively.
