| Abstract: | Through the analysis and calculation on the diffraction phenomenon of self-focus lens, it is explained that round-hole Fresnel diffraction of divergent spherical wave causes this phenomenon. And a concision method to measure the quality of self-focus lens is suggested based on such phenomenon. |

| Keywords: | gradient refractive index self-focus lens round-hole Fresnel diffraction |
