摘要	利用电子光学仿真软件CST模拟设计了一种超小型光离子成像仪，在仿真中采用单透镜聚焦系统对离子进行聚焦。同时，模拟了离子在离子聚焦透镜中的飞行轨迹，仿真分析了离子透镜的能量分辨率，结果表明：相同位置不同速度的离子在MCP处位于同一圆环，相同速度不同位置的离子在MCP处汇聚于一点，离子透镜的能量分辨率高于4%，满足光解动力学等应用领域离子速度成像仪对超小型离子透镜的应用需求。
Abstract	The design of a miniaturized optical ion imager was simulated using the electronic optical simulation software CST. In the simulation, a single lens focusing system was employed to concentrate the electrons. Additionally, the flight trajectories of ions within the ion focusing lens were simulated, and the velocity resolution and energy resolution of ion velocity imaging were analyzed. The results indicated that the energy resolution exceeds 4%, while the velocity resolution exceeds 2%. These findings meet the application requirements for miniaturized ion lenses in fields such as photodissociation dynamics.
