Abstract:
1. A variable focus optical apparatus, comprising: a rigid, curved, transparent optical component having a front surface and a back surface; two transparent, distensible membranes attached to a periphery of the rigid optical component to define two cavities, a first cavity between the rigid optical component and a first membrane and a second cavity between the first membrane and a second membrane; a variable amount of fluid filling each of the cavities; a first reservoir containing additional fluid and in fluid communication with at least one of the cavities, wherein the first reservoir is configured to provide injection of fluid into the at least one cavity or withdrawal of fluid out of the at least one cavity in response to a force or an impulse; a second reservoir containing additional fluid and in fluid communication with at least one of the cavities, wherein the second reservoir is configured to provide injection of fluid into the at least one cavity or withdrawal of fluid out of the at least one cavity in response to a force or an impulse; wherein the front surface of the rigid optical component and the back surface of the rigid optical component are curved in the same direction, and wherein the radius of curvature of the front surface is smaller than the radius of curvature of the back surface such that the intersection of the front surface and the back surface is the circumferential edge of the rigid optical component.
