  • Image capturing lens system, image capturing unit and electronic device
    Patent number: 11630289
    Abstract: An image capturing lens system includes three lens groups including five lens elements. The three lens groups are, in order from an object side to an image side: first, second and third lens groups. The five lens elements are, in order from the object side to the image side: first, second, third, fourth and fifth lens elements. The first lens element has an object-side surface being convex in a paraxial region thereof. The second lens element has negative refractive power. At least one lens element has an inflection point. A focal length of the image capturing lens system is varied by changing axial distances between the three lens groups in a zooming process. The image capturing lens system has a long-focal-length end and a short-focal-length end. The second lens group is moved relative to the first lens group along an optical axis in the zooming process.

  • Near-eye display device
    Patent number: 11500215
    Abstract: A near-eye display device is provided, including a display light source, a rotation module and a refractive amplification component. The rotation module rotates around the rotation center axis. The rotation module is provided with a light source scanning component and a mirror group. The light source scanning component converts the light of some pixel points of the display light source into radial propagation, and then the light is emitted through the mirror group and the refractive amplification component. The light source scanning component turns the light of some pixel points of the display light source into radial propagation, so that the optical path becomes radial direction from axial direction, and increases the optical path distance without increasing the volume of the device, which is conducive to reducing the thickness and volume of the device.

  • Eyepiece architecture incorporating artifact mitigation
    Patent number: 11422364
    Abstract: Techniques for artifact mitigation in an optical system are disclosed. Light associated with a world object is received at the optical system, which is characterized by a world side and a user side. Light associated with a virtual image is projected onto an eyepiece of the optical system, causing a portion of the light associated with the virtual image to propagate toward the user side and light associated with an artifact image to propagate toward the world side. A dimmer of the optical system positioned between the world side and the eyepiece is adjusted to reduce an intensity of the light associated with the artifact image impinging on the dimmer and an intensity of the light associated with the world object impinging on the dimmer.
