Abstract
A variable-profile optical device includes a light-transmission elastic member in which an elasticity of a first surface is set to be higher than that of a second surface disposed opposite to the first surface, wherein a pressure is applied to the second surface of the elastic member, so that the second surface of the elastic member is selectively deformed, and a focus distance may be varied.
