A new theoretical method of realizing real-time manipulation of the optical cage by changing the hybrid polarization states of a double-ring-shaped hybridly polarized vector beam is proposed. The hybrid polarization states can be formed by a double-ring-shaped radially polarized beam through a wave plate. The intensity distribution of the focused double-ring-shaped hybridly polarized vector beams is numerically simulated in the vicinity of the focal plane by using Richards-Wolf vectorial diffraction method. The results show that the optical cage can be formed when the phase delay angle is zero, and the optical cage can be real-time manipulated when the phase delay angle is not zero. The polarization state can be changed by adjusting the phase delay angle of the liquid crystal variable retarder, which can be continuously varied from 0 to π. The realization and manipulation of the optical cage in real time aroused by the phase delay angle will have great potential applications in the field of micro-manipulation.
