我们提出了一种基于球面波合成的新型三维显示器的新概念和首次实验结果。该装置包括一个孔径在毫米范围内的透镜阵列（LA）和一个液晶显示（LCD）面板。LCD的每个像素产生一个向观察者传播的球形波切割。在显示过程中，通过改变LA与LCD之间的距离或调整透镜的焦距，可以动态地改变球面波的曲率。由于该系统与全息摄影类似，旨在近似自然场景的波前，因此它为观察者提供了真实的深度信息，从而避免了任何收敛调节冲突（VAC）。
We present a novel concept and first experimental results of a new type of 3D display, which is based on the synthesis of spherical waves. The setup comprises a lens array (LA) with apertures in the millimeter range and a liquid crystal display (LCD) panel. Each pixel of the LCD creates a spherical wave cutout that propagates towards the observer. During the displaying process, the curvature of the spherical waves is dynamically changed by either changing the distance between LA and LCD or by adapting the focal lengths of the lenses. Since the system, similar to holography, seeks to approximate the wavefront of a natural scene, it provides true depth information to the observer and therefore avoids any vergence–accommodation conflict (VAC).
