Abstract: A method for operating a high-resolution headlamp of a vehicle, the headlamp being configured to project an image into the outer region of the vehicle. At least two regions are selected in the image to be projected which have the same brightness gradients. The brightness gradients of the at least two regions are analyzed in the projection to be carried out. If, during the analysis, a difference in the brightness gradients between individual ones of the selected regions is detected in the projection to be carried out, the headlamp is controlled in such a way that the brightness gradients of the selected regions in the projection to be carried out are matched to each other.

Abstract: A lighting device for a motor vehicle, in particular a headlamp device for a motor vehicle, comprising a first headlamp, which includes a first light module for generating a first light distribution as well as a second light module for generating a second light distribution, the first light distribution of the first headlamp having a higher resolution than the second light distribution of the first headlamp, as well as comprising a second headlamp, which includes a first light module for generating a first light distribution as well as a second light module for generating a second light distribution, the first light distribution of the first headlamp having a higher resolution than the first light distribution of the second headlamp and than the second light distribution of the second headlamp.

Abstract: Device for homogenizing a laser beam including a first substrate with a first lens array including a plurality of cylindrical lenses and a second substrate with a second cylindrical lens array, which is arranged in the beam path downstream of the first substrate and includes a plurality of cylindrical lenses. Exactly one of the cylindrical lenses of the second lens array is assigned to each of the cylindrical lenses of the first lens array. Center-to-center distances between the cylindrical lenses of the first lens array are greater than the center-to-center distances between the cylindrical lenses of the second lens array. A lens vertex of a central one of the cylindrical lenses of the first lens array is aligned with a lens vertex of a central one of the cylindrical lenses of the first lens array that is assigned thereto.

Abstract: A method for determining the pH of liquids by a pH difference measurement of a solution under test and a reference solution and an apparatus for determining the pH of liquids is provided which can determine the pH with a precision equal to or better than 0.001 pH. The method and apparatus are especially useful for determining the pH and development speed of developers for positive photoresists.
