ABSTRACT:
A method of fabricating a one-way transparent optical system by which external light is effectively intercepted and internal light passes nearly without loss is provided. The method includes: forming a silver halide on a transparent substrate; aligning a mask in which a predetermined pattern is formed, on the transparent substrate and exposing the silver halide using the mask; developing and fixing the exposed silver halide and forming a plurality of light-absorbing materials on the transparent substrate; and forming protrusion structures having a shape of a convex lens shape for refracting incident light toward a corresponding light-absorbing material of the light-absorbing materials, on the transparent substrate on which the light-absorbing materials are formed.
