Abstract: The invention relates to a diffractive optical element with a spatial variation in the refractive index, wherein a sequence of adjacent sections, which form a diffractive structure, is formed by the spatial variation in the refractive index, within which sections the refractive index varies in each case. Over a spectral range extending over at least 300 nm, the diffractive structure has a diffraction efficiency of at least 0.95, averaged over the entire spectral range. The value of the diffraction efficiency of at least 0.95, averaged over the entire spectral range, is realized by a single single-layer diffractive structure with an optimized combination of at least two refractive indices and at least two Abbe numbers within each section of the sequence of adjacent sections. The refractive index variation can be achieved by means of doping, material mixing, or structuring into sub-wavelength ranges.

Abstract: A device for two-dimensionally scanning beam deflection of a light beam has spectrally tunable light source that emits a light beam having a time-varying wavelength. The device further comprises a first optical component that produces a first beam deflection. The first beam deflection causes the light beam to be deflected wavelength-dependently in a first direction. A second optical component produces a second beam deflection which causes the light beam to be deflected in a second direction different to the first direction. The second optical component comprises a prism pair comprising two prisms that are rotatably arranged successively in a beam path of the light beam. The two prisms are configured to perform continuous counter-rotational movements.

Abstract: Sensor data are received from a multiplicity of sensors, wherein the multiplicity of sensors image a common scene using a multiplicity of measurement modalities. For each sensor of the multiplicity of sensors, at least one corresponding feature is determined in the respective sensor data and corresponding performance specification data are also obtained. In addition, mutual correspondence analysis between the features of the sensor data is carried out taking into account the corresponding performance specification data. Sensor fusion is also carried out on the basis of the correspondence analysis.

Abstract: It is an object of the invention to improve processes, apparatuses and systems for measuring a measured variable. To this end, a measured variable is measured in a measuring process on the basis of an NV center as a quantum sensor. The NV center has a plurality of quantum states and is optically excitable on the basis of an occupancy of one of the quantum states into at least one excited state of the quantum states by means of an excitation light. The at least one excited state can decay at least with emission of emission light of the NV center. In the measuring process, the NV center is irradiated by the excitation light, the excitation light having a time periodic modulation, and a respective occupancy probability and/or a respective lifetime of the quantum states depending on the measured variable and the excitation light.

First measurement points are defined on a 3D model of a person's head, and a model of a frame is adjusted on the basis of the first measurement points. Defining the first measurement points includes defining second measurement points on a parametric head model, adjusting the parametric head model to the 3D model of the person's head, and determining the first measurement points on the basis of the second measurement points and the adjustment. In this way, the second measurement points only have to be defined once on the parametric model so that the first measurement points can be defined for a plurality of different 3D models of different heads.
