The invention relates to a device for optical 3D measurement of an object using an optical depth-scanning measurement method, comprising at least two light sources, at least two optical means for producing textured patterns and at least one recording means. A first pattern is produced with the aid of a first optical means and projected onto the object to be recorded as a first projection beam. A second pattern is produced with the aid of a second optical means and projected onto the object to be recorded as a second projection beam. The imaging optics is controlled and adjusted in such a way that a sharp focal plane is incrementally varied along an optical axis of the device.

Device for optical 3D measuring of an object

Disclosed is a method for reading a two-dimensional code () by means of a camera () used for the three-dimensional optical measurement of an object using triangulation. Said method comprises the steps of placing the camera () above the two-dimensional code (), having a white light source () of the camera () illuminate the code (), having the camera () capture an image () of the code (), and having an arithmetic unit () read data encrypted in the code () from the image () of the code ().

Method for reading a two-dimensional code by means of a camera used for three-dimensional optical measurement of objects

A method and apparatus for forming an overall image of an object from a plurality of images. Each image includes three-dimensional data and color data and is segmented based on the color data to identify a first region with hard tissue and a second region with soft tissue. For each image, first and second weighting factors may be assigned. Points in the second region with a larger distance to a corresponding proximate part of the first region may have a smaller second weighting factor than a point with a smaller distance to a corresponding proximate part of the first region. The second weighting factor may be variable, with its value dependent upon a value of a first area section corresponding to the first region.

The invention relates to processes and devices for detecting an analyte in a sample by fluorescence measurement of a fluorophore, wherein the detection medium which contains a fluorophore or a precursor of the fluorophore is admixed with an absorber whose absorbance spectrum superimposes the fluorescence excitation range of the fluorophore. The system consisting of the fluorophore and the absorber, which is produced in the detection medium, has an altered effective fluorescence excitation range with an altered fluorescence excitation maximum. Illumination with fluorescence excitation light can take place within the range of this altered excitation maximum. The measured signal obtained from determining fluorescence emission exhibits only low dependence on the wavelength of the excitation light.
