The invention relates to an optical device () for enhancing the resolution of an image or for reducing speckle noise.

Optical device for enhancing resolution of an image or for reducing speckle noise

The invention relates to an optical device () for enhancing the resolution of an image, comprising: a transparent plate member () configured for refracting a light beam () passing through the plate member (), which light beam () projects an image comprised of rows and columns of pixels (), a carrier () to which said transparent plate member () is rigidly mounted, wherein the carrier () is configured to be tilted between a first and a second position about a first axis (A), such that the plate member () is tilted between the first and the second position about the first axis (A), whereby said projected image () is shifted by a fraction (&#x394;P) of a pixel, particularly by a half of a pixel, along a first direction (x), and an actuator means () that is configured to tilt the carrier () and therewith the plate member () between the first and the second position about the first axis (A).

Optical device for enhancing resolution of an image

The invention relates to a lens () for vision correction, wherein the lens () is particularly configured to be placed directly on the surface of an eye () of a person, wherein the lens () further comprises: a transparent base element () having a back side (), and a front side () facing away from the back side (), a transparent and elastically expandable membrane () connected to said base element (), wherein said membrane () comprises a back side () that faces said front side () of the base element (), a ring member () connected to said back side () of the membrane () so that the ring member () defines a curvature-adjustable area () of the membrane (), and wherein the lens () comprises a lens volume () adjacent said curvature-adjustable area () of the membrane (), which lens volume () is delimited by the ring member (), and wherein the lens () comprises a reservoir volume () arranged in a boundary region () of the lens (), wherein said two volumes () are each filled with a transparent liquid (), and a pumping means () configured to transfer transparent liquid () from the reservoir volume () to the lens volume () such that the curvature of said curvature-adjustable area () of the membrane () increases and the focal length of the lens () decreases, and optionally a rigid support structure () that is configured to reduce or prevent compression of the reservoir volume () when an eyelid of the user rests on said boundary region () of the lens.

Lens comprising an adjustable focus length

The invention relates to an optical device for reducing speckle noise of laser light having a first optical element extending along an extension plane, and an actuator designed for moving the first optical element along the extension plane. The actuator is formed as a reluctance actuator that is designed to exert a reluctance force on the first optical element to move the first optical element along the extension plane.

Optical device for reducing speckle noise

The inventive ozone generator comprises at least one tubular external electrode (), at least one internal electrode (), wherein each internal electrode consists of a plurality of tubular metal segments () which are closed at least partially at each end and externally ceramic-coated, said tubular segments are disposed one behind another, mechanically de-coupled from each other and electrically connected, a rod () axially crosses the tubular segments () and is provided on the end thereof with means () for axially clamping the tubular segments to each other in such a way that an electric contact is formed. Each tubular metal segment () is provided at each end thereof with an outwardly convex bottom () which is embodied substantially in the form of a spherical cap, comprises a central area () for electric contact and is provided with a ceramic coating () consisting of at least two thin layers ().
