  • An example of a suitable lens for these applications is disclosed in WO2004/051323, and is shown in Fig. 1.
  • This lens comprises two immiscible fluids A and B, one of which is an electrically susceptible fluid, which means that the wetting of this fluid on the inner wall of the chamber 5 increases if an electrical field is applied.
  • the lens further comprises replica lenses 4 and 6 on either side of the chamber, which may operate as lids to the chamber or may be separate lenses.

Consequently, by the application of different voltages V1 and V2 across the annular electrode 12 and the first electrode 2a and the second electrode 2a' respectively, the contact angles 61 and 62 of the interface 14 with the coating 10 on the inner wall of the chamber 5 have different values, thus yielding a lens having a tilted interface 14 with respect to the optical path 1.
  • the focal point of this variable focus lens not only can be varied in depth by a variation of the strength of the applied voltage, but the focal point can also be changed in a direction perpendicular to the optical axis by variation of the difference in the voltage applied to the first electrode 2a and the second electrode 2a'.
  • the response time of a change in focus for such a lens typically lies in the (sub)millisecond domain, which makes these lenses extremely suitable for use in object tracking application domains.
  • Various known combinations of fluids suitable for application in such a lens are readily available; as an example, a combination of an aqueous salt solution, e.g. aqueous KCI, and a silicon oil or an alkane may be used.
  • the electrodes may be made of known conductive material, e.g. IndiumTinOxide (ITO), whereas the coating 10 may be a teflon coating such as AF1600 supplied by the DuPont chemical company or a parylene stack; various alternative embodiments are readily available in the prior art.

  • the present invention uses a combination of these lenses in a non-obvious way, because WO2004/051323 is completely silent about the use of more than one lens in an electronic device, and is also completely silent about the usefulness of these lenses in object tracking applications. Furthermore, the present invention is based on the realization that the mechanical tilting of complete cameras in the prior art arrangements can be replaced by liquid-based tilting inside the lens of such a camera, which is an improvement that is neither disclosed nor suggested in the prior art.
