Abstract
The disclosed optical lens assemblies may include a deformable element, a structural support element, a substantially transparent deformable medium positioned between the deformable element and the structural support element, a compliant peripheral component positioned between peripheral portions of the deformable element and the structural support element, and an actuator configured to displace at least a portion of the compliant peripheral component to deform the deformable element and change at least one optical property of the optical lens assembly. Related head-mounted displays and methods of fabricating such optical lens assemblies are also disclosed.
Claims20
An optical lens assembly, comprising:
- a deformable element including a substantially transparent deformable medium and a compliant peripheral component;
- and
- at least one electromechanical actuator configured to displace at least a portion of the compliant peripheral component to deform the deformable element and change at least one optical property of the optical lens assembly, wherein the at least one electromechanical actuator is configured to tension a cable to apply a force with the cable to the compliant peripheral component.
A head-mounted display, comprising:
- a support housing;
- an optical lens assembly coupled to the support housing, the optical lens assembly comprising:
- a deformable element including a substantially transparent deformable medium positioned and a compliant peripheral component;
- and
- an electromechanical actuator configured to displace at least a portion of the compliant peripheral component to deform the deformable element and change at least one optical property of the optical lens assembly by tensioning a cable to apply a force with the cable to the compliant peripheral component;
- and
- a display element coupled to the support housing.
A method of altering at least one optical property of an optical lens assembly, comprising:
- tensioning a cable with an electromagnetic actuator;
- displacing, as a result of tensioning the cable, at least a portion of a compliant peripheral component of a deformable optical element;
- and
- deforming, as a result of the displacement of the compliant peripheral component, the deformable optical element to change at least one optical property of the optical lens assembly.
