阅读说明：本技术 用于头戴式显示器中的散光校正的系统和方法 (System and method for astigmatism correction in head mounted displays ) 是由 伊万·M·理查兹 高卫华 王道智 于 2019-02-26 设计创作，主要内容包括：所公开的系统可以包括：(1)透镜组件,该透镜组件响应于至少一个第一控制信号,在显示设备和观看者的眼睛之间的光路上提供沿着电子可控轴位定向的电子可控柱镜度；以及(2)控制器,该控制器(a)接收指示观看者的眼镜处方的柱镜度分量和柱镜轴位分量的信息,以及(b)基于该信息生成该至少一个第一控制信号以使得透镜组件为观看者提供沿着柱镜轴位分量定向的柱镜度分量。还公开了各种其他系统和方法。(The disclosed system may include: (1) a lens assembly responsive to at least one first control signal to provide an electronically controllable cylindrical power oriented along an electronically controllable axis in an optical path between the display device and the eye of the viewer; and (2) a controller that (a) receives information indicative of a cylinder power component and a cylinder axis component of a viewer's eyeglass prescription, and (b) generates the at least one first control signal based on the information to cause the lens assembly to provide the viewer with the cylinder power component oriented along the cylinder axis component. Various other systems and methods are also disclosed.)
