Abstract: A liquid lens structure has an adjustable and continuous range of optical power. The liquid lens structure comprises a substrate layer and a deformable membrane which enclose a volume of liquid. The substrate layer is at least partially transparent in the optical band. The deformable membrane comprises a ground layer, two membrane layers, and two conductive layers. Each of the two conductive layers control electrical voltage applied to one of the membrane layers in reference to the ground layer, wherein each membrane layer deforms in response to applied electrical voltage. The deformation of the two membrane layers adjusts a curvature of the deformable membrane which provides the adjustable continuous range of optical power to the liquid lens structure.

Abstract: An optical element can be adjusted using a displacement element in an actuator assembly. The actuator assembly includes a plurality of lead screws and a mechanical linkage configured to simultaneously rotate the lead screws. The actuator assembly further includes a displacement element configured to act upon the optical element, through translational motion of the displacement element in response to rotation of the lead screws. Multiple optical elements can be adjusted simultaneously using respective displacement elements. In some embodiments, a controller determines a target position for at least one displacement element, where the target position is configured to provide a desired optical characteristic such as an optical power. The controller can apply power to the actuator to move the at least one displacement element. The controller can also shut off power upon detecting that the at least one displacement element has reached the target position or an end-of-travel position.

Abstract: An eyebox region is illuminated with first coherent light and second coherent light having a different wavelength than the first coherent light. A first self-mixed interferometer (SMI) signal is generated in response to first feedback light received back from the eyebox region. A second SMI signal is generated in response to second feedback light received back from the eyebox region. Eye data is generated in response to at least the first SMI signal and the second SMI signal.
