音响和显示器：使用多层显示校正光学像差Correcting for Optical Aberrations using Multilayer Displays
Fu-Chung Huang, Douglas Lanman, Brian A. Barsky, Ramesh Raskar 采用多层显示修正老花眼。个人观察老花眼的距离为45厘米的手表。由于范围受限，手表会失焦。必须佩戴一个+2.50屈光度球面镜片看手表，矫正眼镜（例如，双光眼镜）。（左）作为一个替代的眼镜，手表可以修改为使用含有两个半透明的，发光面板的层叠型显示。这些层上显示的图像的预滤波的手表表面，使得出现焦点时，由散焦眼观察。（右），从左至右依次为沿底部行：使用现有的显示（例如，未修改的LCD），使用现有的单层预滤波的方法，和使用所提出的多层预滤波方法。形象表盘显示相应的图像的顶部行。两层预过滤，同时增加了手表6毫米的厚度，提高对比度和消除振铃的工件，相比现有单层预过滤方法。 （钟表图像c天美时集团美国公司） Correcting presbyopia using multilayer displays. A presbyopic individual observes a watch at a distance of 45 cm. The watch appears out of focus due to the limited range of accommodation. To read the watch, corrective eyewear (e.g., bifocals) must be worn with a +2.50 diopter spherical lens. (Left) As a substitute for eyewear, the watch can be modified to use a multilayer display containing two semi-transparent, light-emitting panels. The images displayed on these layers are pre-filtered such that the watch face appears in focus when viewed by the defocused eye. (Right) From left to right along the bottom row: the perceived image using a conventional display (e.g., an unmodified LCD), using prior single-layer pre-filtering methods, and using the proposed multilayer pre-filtering method. Corresponding images of the watch face are shown along the top row. Two-layer pre-filtering, while increasing the watch thickness by 6 mm, enhances contrast and eliminates ringing artifacts, as compared to prior single-layer pre-filtering methods.
