Abstract
An optical system includes a first deformable lens having a membrane with a deformable portion. A sensor is configured to receive the light focused by the first deformable lens. An optical path extends through the first deformable lens and to the sensor. The first deformable lens is tuned according to an applied electrical signal in order to directly focus light traversing the optical path onto the sensor. A first volume of a first optical media and a second volume of a second optical media are defined at least in part by the deformable portion of the membrane. The first volume and the second volume are completely enclosed by the housing. The first volume and the second volume remain substantially constant for all configurations of the first deformable lens.
