Abstract
An apparatus having an asymmetric adjustable lens with a deformable optical element. The apparatus may also include one or more actuators coupled to a deformable element of the asymmetric adjustable lens in a direct-drive configuration such that (1) mechanical action of the one or more actuators applies force to the deformable optical element and (2) the force applied by the mechanical action of the one or more actuators changes an optical property of the asymmetric adjustable lens by deforming the deformable optical element. Various other devices, systems, and methods are also disclosed.
Claims20
An apparatus, comprising:
- an adjustable lens assembly, comprising:
- a first adjustable lens comprising a first deformable optical element;
- a second adjustable lens comprising a second deformable optical element;
- a first actuator coupled to the first deformable optical element such that mechanical action of the first actuator applies a force to the first deformable optical element;
- and
- a second actuator coupled to the second deformable optical element such that mechanical action of the second actuator applies a force to the second deformable optical element;
- a display element situated between the first adjustable lens and the second adjustable lens;
- a sensor positioned to measure a state of at least one of the first or second adjustable lens;
- and
- a controller configured to actuate at least one of the first or second actuators via closed-loop control based on data received from the sensor.
An apparatus, comprising:
- an adjustable lens assembly, comprising:
- a first adjustable lens comprising a first deformable optical element;
- a second adjustable lens comprising a second deformable optical element;
- a first actuator tangentially mounted along a perimeter of the first deformable optical element such that mechanical action of the first actuator applies a force to the first deformable optical element at a discrete point on the perimeter of the first deformable optical element;
- and
- a second actuator tangentially mounted along a perimeter of the second deformable optical element such that mechanical action of the second actuator applies a force to the second deformable optical element at a discrete point on the perimeter of the second deformable optical element;
- and
- a display situated between the first adjustable lens and the second adjustable lens.
A method comprising:
- receiving an indication of an adjustment to be made to an optical property of a first deformable optical element positioned between a see-through display and a user's eye;
- receiving an indication of an adjustment to be made to an optical property of a second deformable optical element positioned on an opposite side of the see-through display from the first deformable optical element;
- and
- in response to receiving the indications of the adjustments, applying a first force to the first deformable optical element with a first actuator and applying a second force to the second deformable optical element with a second actuator,
- wherein the indication of the adjustment to be made to the optical property of at least one of the first deformable optical element or the second deformable optical element is based on user input.
