Abstract
A focus module contains a boundary element and a focus element. The focus element includes a fluid and a deformable membrane, with the fluid being entrapped between the boundary element and the deformable membrane. The focus module also includes a pressure element, which is capable of deforming the focus element by pressing on the deformable membrane in the direction of the boundary element.
Claims20
An optical system comprising:
- an illumination assembly for generating light to illuminate a target;
- an image sensor for converting light reflected from the target into electrical signals;
- a focus module for focusing light reflected from the target onto the image sensor, the focus module comprising;
- a boundary element;
- a focus membrane;
- and
- a focus fluid entrapped between the boundary element and the focus membrane;
- a deforming element in communication with the focus module, the deforming element comprising:
- a ring shaped structure;
- and
- a plurality of tabs extending inward from the ring shaped structure for applying a force to the focus membrane to change the focus membrane's curvature by curling in the direction of the focus membrane;
- and
- a lens controller coupled to the deforming element for providing a control signal to the deforming element to vary the force applied to the focus membrane.
