呼呼, 解釋的很完整唷, 補充一下我的經驗
去紐約的 IMAX 電影院, 看了幾部電影
都是所謂的IMAX 3D, 因此, 需要戴上立體眼鏡
不過這跟我們一般的簡單型立體偏光鏡可以大大不同!! 說出來可是驚人!
首先, 這眼鏡可不能讓你看完帶回家, 因為可是要不少錢的! 除了左右眼的偏光鏡片之外, 進場前, 還會要你先檢查有沒有電.....沒錯, 有沒有電! 因為立體眼鏡, 上頭還有感應器, 以便讓你可以看到最佳的畫面(好像可以感應閃動頻率)
IMAX 3D WITH ELECTRONIC CLASSES
Instead of superimposing images, two sets of shutters within the 3D projector switch back and forth at 96 times per second, to project alternate left and right eye images on the screen. During the presentation, E3D glasses sense a signal from the projector. In response to this signal, the left and right eye shutters in the glasses alternately open and close in conjunction with the projector shutters to make sure each eye sees the appropriate image, ultimately creating the 3D effect.
