Abstract
In this paper, a novel design of the illumination optical system for a laser target simulator is investigated to determine the optimal relationship between the uniformity of the illumination system and the energy utilization in a laser target simulator. First, the optimal size of the fly-eye lens unit is calculated from the parameters of the DMD to improve the energy utilization of the system; second, the optimal parameters of the TIR prism group are calculated based on the size of the illuminating beam and the optimal deflection angle of the TIR prism group is analyzed, which results in the compact overall structure of the system and improves the uniformity under the premise of ensuring that there is not much change in the energy utilization; and finally, the optimal design of the illumination optics system for laser target simulators is investigated based on the Finally, based on the Scheimpflug principle, the uniformity of the illumination system is further improved by solving the deformation of the image plane caused by the insertion of the TIR prism group. The results show that the simulation results of the system's uniformity reach 96.93%, the simulation results of the energy utilization are 60.05%, and the structure is compact, and the system designed by this method can provide a good design solution to obtain high energy utilization and uniformity.
