The influence of a perfect cloaking device on light and the basic principle of geometric optical cloaking are discussed．The feasibility of four-lens cloaking device and the requirements of structural parameters are proved by geometric optical transmission matrix．The optical cloaking performance of the four-lens system is verified by experiments，and the influence of the lens focal length，diameter and object shape on the cloaking effect is discussed．
