  • Patent number: 10705264
    Abstract: A varifocal lens module, consisting of a casing provided with a holding chamber, an opening end, an interconnecting hole, a soft lens disposed on the casing to seal the holding chamber, and a medium control device connects to the interconnecting hole. The soft lens is provided with a first curved surface having a first curvature exposed external of the casing and a second curved surface having a second curvature positioned interior of the holding chamber corresponding to the first curved surface. The medium control device is connected to the interconnecting hole for controlling the volume of the medium inside the holding chamber, whereby the change in volume of the medium changes the compression on the second curved surface, thereby modifying the second curvature of the second curved surface, producing a variation in the spacing between the second curved surface and the first curved surface to achieve a varifocal effect.

  • Patent number: 10444491
    Abstract: A variable focal length optical assembly may include a deformable entry lens element, a deformable first reflective element and a deformable second reflective element. Using a controller coupled to the deformable elements, an external force such as a mechanical, electrical, electromechanical, or electromagnetic force is applied to the deformable elements to provide any number of different focal lengths. Since the deformation of the deformable elements, and consequently the changes in focal length, occur much faster than the playback frame rate, a number of sub-frames, each containing an image obtained at a different focal length, are associated with each playback frame. The availability of multiple images in the form of sub-frames permits the selection of an optimal image for inclusion in the final playback frame sequence. The availability of multiple images in the form of sub-frames at different focal lengths also permits the seamless incorporation of zoom-in and zoom-out effects.

  • Patent number: 9364319
    Abstract: A lens in accordance with the present invention includes an switchable cell consisting of optical substrate with diffraction surface, elastic film in contact with the diffraction surface of the substrate, optical fluid that fills the space between the film and diffraction surface and the mean to transfer the optical fluid in and out of the space between the film and diffraction surface. The refractive index of the optical fluid matches the refractive index of the optical substrate. The switchable cell changes focus positions between refractive focus in relaxed state when the pressure at both sides of the film is the same and diffraction focus when the optical fluid is transported from the space between the film and optical substrate for the film to largely conform to the diffraction surface shape of the optical substrate.

  • Patent number: 9335539
    Abstract: A pixel device using optically active fluid contained within elastomeric materials and actuated through dielectric elastomer membrane is disclosed. The underlying mechanism of optical contrast in this display pixel is the spread and contraction of the fluid contained within a pre-stretched elastomer membrane and a substrate. The actuation mechanism for the fluid flow is a dielectric elastomer membrane coated with compliant electrodes on both sides. When both electrodes are connected to a voltage source, the oppositely charged electrodes attract each other, compressing the sandwiched elastomer membrane in the thickness direction but increasing its lateral dimension. Due to geometrical constraint, the change in the membrane lateral dimension results in the net volume change of the fluid reservoir, causing optically active fluid to move from the display cavity into the fluid reservoir or vice versa.
