基于多透镜组近轴隐形条件，应用图像交叉法求解了四透镜组和五透镜组的隐形距离，并根据计算结果搭建了透镜组实验，对隐形范围进行了测量，讨论验证了计算结果. 最后，采用COMSOL模拟了多透镜组在平行光下的几何光路图，进一步讨论了不同透镜间隐形范围，其结果与实验测量以及理论计算完全吻合. 

Based on the paraxial invisibility condition of multiple lens system, the invisibility distances of four-lens system and five-lens system are calculated by using the image intersection method, and the lens system experiment is built according to the calculation results. The invisibility range is measured and discussed to verify the calculation results. Finally, COMSOL is used to simulate the geometric optical path of multiple lens system in parallel light, and the invisibility range between different lenses is further discussed. The results are in good agreement with the experimental measurements and theoretical calculations.
