Abstract
A fluid lens includes a refractive interface positioned between two transparent plates where at least one surface of one of the plates has a fixed radius of curvature configured to compensate for aberration produced by the fluid lens. The refracting interface can be formed by a meniscus formed between two immiscible liquids or by a membrane positioned between two fluids. A method of reducing aberration of a fluid lens includes determining a fixed radius of curvature for at least one surface of one of the plates that is sufficient to compensate for aberration produced by the fluid lens.
Claims21
A fluid lens comprising:
- a refracting interface positioned between a first fluid and a second fluid enclosed in a chamber;
- a first transparent plate comprising a surface with a fixed radius of curvature;
- and
- a second transparent plate;
- wherein the refractive interface is positioned between the first transparent plate and the second transparent plate;
- and
- wherein the fixed radius of curvature is configured to compensate for aberration produced by the fluid lens.
(canceled)
A method of reducing aberration of a fluid lens, the method comprising:
- determining a fixed radius of curvature for a surface of a first transparent plate that is configured to compensate for aberration produced by the fluid lens;
- and
- enclosing the refracting interface between the first transparent plate and a second transparent plate in a chamber, the refracting interface positioned between a first fluid and a second fluid in the chamber.
