摘要： The present invention provides thermal compensation for a lens assembly comprising a polymer lens body. Polymers do have different thermal expansion coefficients which makes it necessary to compensate for thermal expansions to keep optical characteristics of such lenses within specifications when used under different environmental conditions. Also, it is necessary to provide thermal compensation during manufacturing of such lenses due to high temperatures during manufacturing steps.

摘要： A 3D image apparatus using a single optical channel for capturing multiple view-angle images of an object for use in generating a 3D image or model of the object. The apparatus includes within the optical train an active optical component, an aperture plate having an aperture, a lens for focusing light from the aperture, and an image sensor. The active optical component has a changeable shape or position for providing first and second optical wavefronts through the aperture and focused by the lens onto the image sensor from first and second view angles of the object. The second optical wavefront is shifted by the active optical component on the image sensor with respect to the first optical wavefront in order to provide multiple view-angle images along the single optical channel, which can be used to generate a 3D model or image of the object.

摘要： A liquid crystal optical device is provided including at least two LC cells. A first LC cell layer has a predominant director orientation imparting a transversally non-uniform phase delay to a first polarization of an unpolarized incident light field passing therethrough while incident light of a second polarization orthogonal to the first light polarization passes therethrough undergoing transversally uniform phase delay. The first LC cell is configured to project a center extraordinary ray onto an optical axis of the device at the image surface. A second LC cell layer has a predominant director oriented orthogonally to the other predominant director in a plane perpendicular to the optical axis. The second LC layer imparts a transversally non-uniform phase delay to the second polarization of the incident light passing therethrough, the second LC cell being configured to project a center ordinary ray onto the optical axis at the image surface.

摘要： Disclosed are apparatuses and manufacturing methods for a fluid filled lens reservoir system. The eyeglass reservoir system includes a temple piece having a cavity, a bladder positioned within the cavity and configured to repeatedly compress and relax, the bladder being made of a flexible material, and a connecting tube coupled to an inlet port of a lens module and to the bladder, configured to carry a fluid between the bladder and a fluid filled lens cavity of the lens module. The eyeglass reservoir system further comprises a compression arm contacting the bladder and configured to transmit force from an actuator to the bladder to cause movement of the fluid between the bladder and the connecting tube. The bladder and connecting tube are made of a flexible material such as polyvinyledende difluoride. The connecting tube further comprises a flared end configured to couple to the inlet port of the lens module.

摘要： A switchable autostereoscopic display device comprises a display panel having an array of display pixels for producing a display, the display pixels being arranged in rows and columns, and a lens arrangement with an array of slanted elongate lenses for directing the output from different pixels to different spatial positions to enable a stereoscopic image to be viewed, the lens arrangement being in a plane parallel to the display panel. The lens arrangement comprises an electrically switchable LC layer which defines a lens pattern or a lens replica pattern, wherein the LC alignment of the LC layer is electrically switchable such that the lens arrangement is switchable between a 2D mode and a 3D mode. In the 2D mode, the LC alignment is in a first direction substantially within the plane of the lens arrangement, and in the 3D mode the LC alignment is in a second, perpendicular direction also substantially within the plane of the lens arrangement. The light output of the display panel is polarized in the second direction. This arrangement enables a perpendicular relationship between the output of the display panel and the LC alignment direction to be maintained for two perpendicular viewing planes.

摘要： In an image display device in which a wavefront-curvature of imaging light can be adjusted using a variable-focus lens, the variable-focus lens can be located at a position suitable for downsizing the variable-focus lens. To this end, the image display device is configured to include: a light source (12) ; an imaging-light generator (14) converting light emitted from the light source, into imaging light representative of the image to be displayed, to thereby generate the imaging light; a relay optical system (16) focusing the imaging light emitted from the imaging-light generator, on an image plane which is located at an optically conjugate position to the imaging-light generator, the relay optical system defining a pupil through which the imaging light passes, within the relay optical system; a variable-focus lens (50) disposed at a position generally coincident with the pupil, the variable-focus lens having a varying focal length; and a wavefront-curvature adjuster (50) configured to vary the focal length by operating the variable-focus lens, to thereby adjust a wavefront curvature of the imaging light emitted from the relay optical system.
