    • An image display system comprises polarization spectacles having different polarization axes with or without .lambda./4-foils of both polarization lenses forward of the eyes of the person to be tested. The system of the invention further includes an image display device for generating light with a specific direction of polarization or a specific rotational direction of the circularly polarized light. The image display device comprises essentially at least one vectograph film and at least one image screen. This arrangement can so influence the light coming from the image screen that test figures or parts thereof can be seen by only one eye or by both eyes. If the image display system is to be used as a vision testing system and the test figures are to be changed, then there is a corresponding command of a drive circuit via a memory. The drive circuit drives the image screen in a suitable manner. A color display can be provided by making an appropriate modification to the image display device.
    • 图像显示系统包括具有不同偏振轴的偏振眼镜,该偏振轴具有或不具有被测试者的眼睛前方的两个偏振透镜的λ/ 4箔。 本发明的系统还包括用于产生具有特定的偏振方向或圆偏振光的特定旋转方向的光的图像显示装置。 图像显示装置基本上包括至少一个矢量图膜和至少一个图像屏幕。 这种布置可以影响来自图像屏幕的光,测试图或其部分只能通过一只眼睛或双眼来看到。 如果图像显示系统被用作视觉测试系统并且测试图被改变,则存在通过存储器的驱动电路的相应命令。 驱动电路以合适的方式驱动图像屏幕。 可以通过对图像显示装置进行适当的修改来提供彩色显示。
