摘　　要：在可见光频段大目标的光学隐形引起了人们的广泛关注。通过实验探究了二、三和四凸透镜系统的光学隐形现象,结果表明:只有四凸透镜系统才能成功实现目标的隐形。同时探究了双凸透镜直径、焦距对四凸透镜系统中目标被检测和隐形范围的影响,结果表明:焦距相同的情况下,采用直径越大的凸透镜,目标被检测到的范围和隐形范围越大;直径相同的情况下,焦距之和越大的凸透镜组合,目标被检测到的范围和隐形范围越大。The optical cloaking of large objects in the visible frequency band has attracted extensive attention. The optical cloaking of two, three and four convex-lens system is explored through experiments, and it is showed that only four convex-lens system can successfully realize the cloaking of the objects. The influence of the diameter and focal length of the biconvex lens on the detection and cloaking range of the object in the four convex-lens system is explored. The results show that when the focal length is the same, the larger the diameter of the convex lens is, the larger the detection and cloaking range of the object are. And with the same diameter, the larger the sum of focal lengths of the convex-lens combination, the larger the detected and cloaking range of the object.
