Abstract
An image magnifying/reducing optical device includes a base member having first and second surfaces which are approximately parallel to one another; and a plurality of high-refractive-index regions formed in the base member. The plurality of high-refractive-index regions continuously extending from the first surface to the second surface of the base member; and a sectional area of each of said plurality of high-refractive-index regions around the second surface being larger than that around the first surface.
Claims46
An image magnifying/reducing optical device comprising:
- a base member having first and second surfaces which are approximately parallel to one another;
