摘要：
In high power laser facilities, the ghost images was usually considered for the spot position and energy density with geometrical optics (GO) but couldn't obtained the ghost images focal spot which was also essential for the ghost images damage threshold. And the energy redistribution on focal spots may induce undesired partial damage as well. Therefore, Collins formula was applying on a single lens to analyze the ghost images focal spot detailed distribution in space. The results were consistent with GO and the output spots on focus were same to Airy spot with different size in different reflection orders.
