Abstract
A cell phone includes: a device for wireless communication; an imager sensor for capturing an image of an object; a lens system for projecting an image of the object onto the imager; a battery for powering the cell phone; a lens system for focusing images of the object onto the imager comprising: a focus element; at least two electrodes associated with the focus element; a control system to adjust the state of focus of the focus element by controlling the at least two electrodes.
Claims20
A cell phone comprising:
- a device for wireless communication;
- a photosensor for capturing an image;
- a battery for powering the cell phone;
- an electrowetting fluid lens for focusing on images using fluids wherein the fluids touch at an interface;
- a control system for altering the shape of the interface to adjust an entrance optical axis angle or direction relative to the fluid lens, the control system having:
- at least two electrodes;
- a controller to generate control signals applied to the electrodes;
- a sensor to influence the control signals to compensate for movement of the cell phone;
- wherein the electrowetting fluid lens is a polarization independent lens is fabricated using two isotropic materials with different dielectric constants and refractive indices.
