麦克斯韦视图显示器可以为视力低下的人提供视觉信息，因为视网膜图像可以独立于眼睛的屈光能力形成，通过使用光线汇聚在瞳孔上。本研究提出了全息麦克斯韦视图显示器。这就产生了一个汇聚在瞳孔上的波前并在视网膜上形成图像。所述光束的会聚点可根据瞳孔的运动而电移动，所述瞳孔中的光束宽度可电改变以控制眼睛的景深。提出了一种用于全息麦克斯韦视图显示的紧凑型光学系统结构。构建了原型系统并进行了实验测试。由于这种全息技术允许瞳孔中的相位调制，因此可以纠正眼睛的像差；因此，视网膜图像可以形成的眼睛散光。(C) 2018年美国光学学会根据OSA开放获取出版协议的条款
The Maxwellian-view display can provide visual information to people with low vision because retinal images can be formed independently of the refractive power of an eye by using rays converging on its pupil. This study presents the holographic Maxwellian-view display. which generates a wavefront converging on the pupil and forming images on the retina. The beam convergent point can be moved electrically in accordance with the pupil movement, and the beam width in the pupil can be changed electrically to control the depth of field of the eye. A compact optical system configuration for the holographic Maxwellian-view display is also proposed. The prototype system was constructed and experimentally tested. Because this holographic technique allows the phase modulation in the pupil, eye aberrations can be corrected; thus, retinal images can be formed for eyes with astigmatism.
