    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: Image stabilization devices and methods are disclosed. In various embodiments, image stabilization is achieved by altering the direction of the optical axis through a flexible lens body by activating actuators attached to the flexible lens body, wherein the amount of applied voltages onto the actuators are proportional to signals provided by motion sensors sensing yawing and pitching movements, respectively.

    摘要: The present invention is generally related to the field of optical systems and/or lens attachments, and more specific to an optical system and/or lens attachment providing a switchable Optical Power Switch (OPS) controllably switchable between different states. A soft transparent material (12), for example silicone-gel is disposed onto a surface of a glass plate (10). The glass plate (10) can be moved with actuators towards a surface of a lens body (10). When the soft material element (12) is in contact with the surface of the lens body (12), this surface changes its optical feature.

    摘要: A method and system providing dynamic contrast control in scanning line color display systems, and particularly a method and system comprising at least two modulator units is disclosed. One modulator unit is for modulating pixel information in a line to be displayed while the other one provides illumination intensity control over different pixel areas or clusters of pixels of said same line to be displayed by using a tunable diffractive grating element (TDG) in the illumination path to provide image source dependent active brightness level control, i.e. ‘dynamic contrast’, as well as a shutter function for pixels off transition periods.
