Publication number: 20240027776Abstract: A lens module may include a first lens element, a lens shaping structure that is coupled to the first lens element, and a plurality of actuators that are configured to adjust a position of the lens shaping structure to adjust the first lens element. The lens module may also include a second lens element and a fluid-filled chamber between the first and second lens elements. To allow dynamic adjustments of the second lens element without requiring additional actuators, the second lens element may be a semi-rigid lens element. When the actuators adjust the curvature of the first lens element, the gauge pressure applied to the second lens element is changed. This causes a change in curvature of the second lens element. The actuators may therefore adjust the curvature of both the first and second lens elements even though none of the actuators are attached to the second lens element.Type: ApplicationFiled: October 5, 2023Publication date: January 25, 2024Inventors: James E. Pedder, Igor Stamenov, Richard J. Topliss, Thomas M. Gregory, Michael D. Simmonds

Patent number: 11822079Abstract: An electronic device may have a display that provides image light to a waveguide. First and second liquid crystal lenses may be mounted to opposing surfaces of the waveguide. An coupler may couple the image light out of the waveguide through the first lens. The second lens may convey world light to the first lens. Control circuitry may control the first lens to apply a first optical power to the image light and the world light and may control the second lens to apply a second optical power to the world light that cancels out the first optical power. Each lens may include two layers of liquid crystal molecules having antiparallel pretilt angles. The pretilt angles and rubbing directions of the first lens may be antiparallel to corresponding pretilt angles and rubbing directions of the second lens about the waveguide.Type: GrantFiled: July 24, 2019Date of Patent: November 21, 2023Assignee: Apple Inc.Inventors: Jin Yan, Young Cheol Yang, Igor Stamenov, Scott M.

Patent number: 11815685Abstract: A head-mounted device may have a display that displays computer-generated content for a user. The head-mounted device may have an optical system that directs the computer-generated image towards eye boxes for viewing by a user. The optical system may be a see-through optical system that allows the user to view a real-world object through the optical system while receiving the computer-generated image or the optical system may include a non-removable lens and a removable vision correction lens through which an opaque display is viewable. The optical system may include a removable lens. The removable lens may serve as a custom vision correction lens to correct for a user's vision defects. The optical system may have a projection bias lens that places computer-generated content at one or more desired virtual image distances and a corresponding compensation bias lens.Type: GrantFiled: March 17, 2021Date of Patent: November 14, 2023Assignee: Apple Inc.Inventors: Victoria C.

Publication number: 20230324676Abstract: A lens module may include a transparent lens element, a lens shaping structure that is coupled to the transparent lens element, and a plurality of actuators that are configured to adjust a position of the lens shaping structure to adjust the transparent lens element. The lens shaping structure may include a plurality of extensions that are each coupled to a respective actuator. To ensure the lens shaping structure has desired curvature between the extensions, the lens shaping structure may have a portion in one or more segments between adjacent extensions that has a property with a different magnitude than an additional portion of the lens shaping structure. The portion between the adjacent extensions may have an increased or decreased rigidity relative to the additional portions. The portion between the adjacent extensions may have a different width, thickness, or Young's modulus compared to the additional portions.Type: ApplicationFiled: January 17, 2023Publication date: October 12, 2023Inventors: Igor Stamenov, Richard J.

Publication number: 20230258944Abstract: A head-mounted device may have lenses. A user may view images through the lenses from eye boxes. The lenses may be tunable liquid lenses. Each lens may have a lens chamber. The lens chamber of the lens may have rigid and/or flexible walls that form optical lens surfaces. Actuators and/or pump and reservoir systems may deform the lens surfaces in response to control signals from a control circuit to tune the lens. Each liquid lens may have oil or other liquid in the lens chamber for that lens. Inorganic dielectric particles or other refractive-index-adjustment particles may be used to adjust the refractive index of the lens. The particles may be subwavelength in size.Type: ApplicationFiled: April 28, 2023Publication date: August 17, 2023Inventors: Sebastien Bolis, Arnaud Pouydebasque, Igor Stamenov, James E.

Publication number: 20210286108Abstract: A head-mounted device may include one or more adjustable lens elements. The adjustable lens element may include a transparent substrate, a collapsible wall that forms an enclosed perimeter on the transparent substrate, and a flexible membrane on the collapsible wall that together define an interior volume. The interior volume may be filled with a fluid. The adjustable lens element may include a lens shaping component that applies a force to the collapsible wall to adjust a height of the collapsible wall relative to the transparent substrate, which in turn may be used to adjust the shape of the flexible membrane and thus the lens power of the lens element. The collapsible wall may have bellows that allow the collapsible wall to fold on itself when compressed, thereby minimizing unintended lateral movement of the collapsible wall.Type: ApplicationFiled: February 4, 2021Publication date: September 16, 2021Inventors: Richard J.
