A spectacle lens for smartglasses can include at least one light source arrangement at the edge of the spectacle lens that emits coherent light, or at least one region at the edge of the spectacle lens for coupling in light from a light source arrangement that emits coherent light, or at least one light source arrangement that is embedded in the spectacle lens. A transparent or partly transparent display can provided to the spectacle lens such that coherent light emanating from the light source arrangement emits coherent light passing through the display or is reflected by the display. The wavefront of the coherent light is modulable in terms of its amplitude and/or its phase by an actuation of the display. A deformation device for deforming the wavefront of the coherent light before or after the modulation by the display can also be provided.

A method for supporting a user aiming at an object with a telescope includes determining and storing a first object position of the object relative to the telescope when a user aims at the object with the telescope and the telescope is located at a first telescope position, and supporting a user when aiming at the object again with the same telescope based on the stored first object position relative to the telescope.

Provided is an optical element with a Fresnel structure with several Fresnel segments. Each Fresnel segment has an optically active facet, the shape of which is part of a predetermined surface. The predetermined surfaces of the optically active facets differ in terms of their curvature profile.

A method for adjusting a display device with a holder that can be fitted on the head of a user includes a front section in which two spectacle lenses are arranged which are connected to each other via a central part, an imaging unit secured to the holder, which generates an image, and an imaging optical system secured to the holder which, when the holder is fitted on the head of the user, images the generated image into an exit pupil such that the user can perceive it as a virtual image with his first eye. The first spectacle lens with the coupling-out section is positioned in such a way that the exit pupil of the imaging optical system coincides at least partially with the pupil of the first eye of the user when the holder is fitted on the head of the user.

A multifocal representation device with a digital image generation module and a control unit, which conveys to the digital image generation module two-dimensional image data of a three-dimensional object to be represented, is provided, wherein the digital image generation module, based on the two-dimensional image data conveyed, generates two-dimensional images of the object from at least two different object planes in corresponding different focal planes in such a way that an observer can focus with his eye on the different focal planes in order to perceive the represented object three-dimensionally, and wherein the control unit determines for each two-dimensional image to be represented a sharpness value in sections and sets the image data to dark for the image sections the sharpness value of which lies outside a sharpness value range predetermined for the image.

An apparatus for image reconstruction comprises an optical system and a control means for controlling the optical system, which control means is configured to control the optical system, for the capture of a plurality of single images, in such a manner that at least one parameter of the optical system is different upon capture of at least two single images. The apparatus comprises a processing device for digitally reconstructing an image in dependence on the plurality of single images and in dependence on information about optical transfer functions of the optical system upon capture of the plurality of single images.

A measuring apparatus and method for determining dimensional characteristics of a measurement object use a sensor head in order to register desired measurement points on the measurement object. The sensor head comprises a polychromatic light source for generating light having various wavelengths of light, a spectrometer, and an optical system having at least one lens element. The optical system produces a first defined range of color dependent foci and a second defined range of color dependent foci in front of the at least one lens element. The spectrometer generates a first spectral information when the measurement object is in the first defined range, and it generates a second spectral information when the measurement object is in the second defined range. An evaluation unit exploits the first spectral range in a coarse measurement mode, and it exploits the second spectral range in a fine measurement mode.

A microscope includes an illumination unit for illuminating a mask at a predetermined non-axial illumination angle, an imaging unit for imaging an aerial image of the mask within a predetermined defocus region, and an imaging field stop, in which as a result of the lateral displacement of the aerial image depending on the position within the defocus region and on the non-axial illumination angle, the opening of the imaging field stop is dimensioned such that the aerial image is either completely encompassed or circumferentially cut within the defocus region. A method for characterizing a mask having a structure includes illuminating the mask at at least one illumination angle using monochromatic illumination radiation such that a diffraction image of the structure is created, recording the diffraction image, establishing the intensities of the maxima of the adjacent orders of diffraction, and establishing an intensity ratio of the intensities.

Microscope and method for characterizing structures on an object

A microscope is provided for space-resolved measurement of a predetermined structure. The microscope includes a source of radiation, which emits electromagnetic radiation of a predetermined wavelength, an optical system, which irradiates the electromagnetic radiation onto the structure to be measured and images the structure, irradiated with the electromagnetic radiation, onto a detector. The optical system has two eigen polarization conditions, and the optical system includes a polarization module by which a polarization condition can be set for the electromagnetic radiation of the source of radiation, the polarization conditions corresponding to the eigen polarization conditions.
