Title:
管状収納器内に可変焦点液体レンズを形成するための方法
Document Type and Number:
Japanese Patent JP2009527795
Kind Code:
A
Abstract:
The present invention provides a variable focus fluid lens wherein the focal length is controllable by changing the contact angle of a fluid meniscus. A liquid (20), such as water, is filled in a tubular housing (10) with an internal surface including adjacent hydrophilic (40) and hydrophobic (30) areas or regions, wherein the boundary between the hydrophilic and hydrophobic regions constrains the liquid (20) and presents a meniscus (50) having a curvature defined, in part, by the static contact angle at the boundary. When a control pressure is applied to the liquid (20), the curvature of the meniscus (50) varies as the contact angle of the liquid changes at the boundary.
