Therefore, instead of incoming light being focused to a perfect geometric point, the diffraction effect spreads the light into a disc with rings surrounding it.

因此，由于衍射存在，我们很难把入射光线集中在一点上，衍射使最终形成一个圆盘或者在外圈形成一个圆环。

Therefore, this research reveals the composition of Airy disc, which is beneficial to deepen and enhance the recognition of the classical diffraction problem.

这一研究揭示了爱里斑的结构，有助于加深和提高对经典衍射现象的认识。
