利用一块曲率半径适当的凹面板可使各种反射图象达到难以觉察的程度。本文将论述这一发展,并引证它给图象、亮度或清晰度带来的损失是最小的。一台电视机,根据其屏幕尺寸,有一最佳收看距离。此值可作为凹面板的最佳焦距,而面板的曲率半径则须两倍于此焦距。
The use of a concave plate with the proper radius of curvature can make all kinds of reflection images reach unobtrusive degree. This article will address this development and cite it to minimize the loss of image, brightness or sharpness. A TV set, based on its screen size, has an optimal viewing distance. This value can be used as the best focal length of the concave panel, and the panel radius of curvature must be double this focal length.
