| Abstract: | The spherical aberration of infrared guided head imaging spot instrument influences the quality of imaging spot. It can reduce the energy distribution. The influence of spherical aberration is studied in this paper. The focusing control func- tion is derived. It can exactly obtain the optimal image plane through automatic convergence, and it is an important segment of quality estimation. |
