Abstract: According to the certain coupling between some Zernike modes in the concentric aperture circle within the unit circle, as well as the counterbalance between each other of the corresponding Zernike modes aberration in certain concentric pupil region, the combined models of Zernike modes are created. According to the decreasing amplitude ratio parameter of aberration RMS in the concentric pupil region, the linear conjugated models of Zernike modes aberration at 4 mm concentric pupil diameter are presented. Each model shares the characteristics of 2 radial orders apart, the same azimuth frequency, the same coefficient sign and the prescribed amount. Through the analysis on the influence of conjugated models on optical quality, it is found that the optical quality is improved significantly after combination. It indicates that the influence of conjugated models combination on optical quality doesnt have superposition, but presents as compensation. Making use of the conjugated models in adaptive optics, the spatial compensation ability of the deformable mirror can be improved, which can undoubtedly inaugurate the new ideas for the correction theory of human eye aberration.
