THREE DIMENSIONAL IMAGE BY UTILIZING CONCAVE MIRROR

摘要

PURPOSE: A three dimensional image by utilizing a concave mirror is provided to realize a mass production thereof with low costs and to manufacture them easily. CONSTITUTION: A three dimensional image by utilizing a concave mirror includes an upper concave mirror and a lower concave mirror. The curvature of the upper concave mirror is equal to that of the lower concave mirror. In order to implement the three dimensional image, the two concave mirrors are arranged in such a way that the central point of one of the two concave mirrors is placed at the focal point of the other concave mirror. The object of the three dimensional image is inserted between the two concave mirrors and the two attached concave mirrors are placed in a horizontal direction. The upper concave mirror is cut in a predetermined size with respect to the focal point. And, the real image is illuminated on the upper concave mirror.
