目前,国外正在研制各种形式的三维立体电视。图1的方法,是把二个电视摄象机所摄取的图象,通过附有偏振光器的两个电视映象机,把图象重叠地映放在一个荧光屏上。这样观众只要坐在离电视机一定距离的地方,戴一付偏振光眼镜,就能收看立体图象了。
At present, various forms of three-dimensional television are being developed abroad. The method of Figure 1 involves superimposing the images picked up by two television cameras on a screen by means of two television imagers attached to a polarizer. So long as the viewer is sitting at a distance from the television set and wearing polarized polarized glasses, he can view stereoscopic images.
