We present a full-color holographic augmented reality near-eye display using a Pancharatnam-Berry phase lens (PBP lens) and its aberration correction method. Monochromatic and chromatic aberrations of the PBP lens are corrected by utilizing complex wavefront modulation of the holographic display. A hologram calculation method incorporating the phase profile of the PBP lens is proposed to correct the monochromatic aberration. Moreover, the chromatic aberration is corrected by warping the image using the mapping function obtained from ray tracing. The proposed system is demonstrated with the benchtop prototype, and the experimental results show that the proposed system offers 50° field of view full-color holographic images without optical aberrations.
我们展示了一种使用潘查拉特纳姆-贝里相位透镜（PBP透镜）的全彩全息增强现实近眼显示器及其像差校正方法。通过利用全息显示器的复波前调制来校正PBP透镜的单色像差和色差。提出了一种结合PBP透镜相位分布的全息图计算方法来校正单色像差。此外，通过使用从光线追迹获得的映射函数对图像进行变形来校正色差。通过台式样机对所提出的系统进行了演示，实验结果表明，该系统提供了50°视场的无光学像差的全彩全息图像。
