目前各式各样的立体图像 演示技术， 均是运用这一原理。 The distance between the two eyes of the person is about 6~7 cm. It can be seen with the same thing. The angle of the rain will not be the same. Although the gap between the two eyes is small, the retina should be transmitted to the brain. The brain uses this tiny gap to produce a sense of distance, and thus produces «: . With one eye, it is also 3⁄4· to the object, the object is 3⁄45, but the distance is not easy to lick. According to this principle, if the same image is used, two images with a slight angular difference are created using the angle of view of the two eyes, and then the two eyes are separately seen.
