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.
Claims5
A variable-profile mirror comprising:
- a flexible thin film having an optical reflective surface;
- a frame member which supports said flexible thin film;
- a substrate which is disposed opposite to said flexible thin film, and which is bonded to said frame member;
- a pressure chamber which includes a space surrounded by said flexible thin film and said substrate, and in which said flexible thin film and said substrate form a portion of a wall;
- a pump device which is disposed opposite to said pressure chamber via said substrate, and which is bonded to said substrate;
- a first channel which extends through said substrate, and which connects said pressure chamber to said pump device;
- and
- a second channel which connects said pump device to the outside,
- wherein said pump device sucks or discharges fluid with respect to said pressure chamber through said first and second channels, and the profile of said flexible thin film may be varied.
